SpiritualThe Journey of the Soul
In the previous chapter, we examined various conceptions of what may await us beyond death. Among them, one stands out for its longevity, universality, and explanatory power: the idea that life continues not in a final resting place, but through a cycle of rebirth. This vision—commonly referred to as reincarnation—portrays death not as an end, but as a turning point in the soul’s ongoing journey. Seen in this light, reincarnation offers a compelling framework to understand our suffering, desires, and destiny. The word reincarnate comes from the Latin re (again) and incarnare (to enter the flesh), and literally means “to re-enter a body of flesh and bone.” It is distinct from the idea of resurrection, which refers to the revival of the same body that was once laid to rest. This book proposes that reincarnation operates according to subtle, knowable laws—more akin to a metaphysical science than to an unverifiable belief. If the transmigration of the soul is real—if we have lived before and will live again aŌer death—then it must be true universally, applying to all beings regardless of time, culture, or personal belief. Conversely, if it is not true, it cannot be true for anyone, even for those who believe in it. This chapter systematically investigates the subtle laws of reincarnation and their implications for our lives. We will explore questions such as: • What exactly happens at the moment of death? • Why don’t we remember our past lives? • How do our actions, thoughts, and desires shape our future birth? • Can animals reincarnate as humans—and can humans be reborn in animal or even plant forms? • What is karma, and how does it govern this cycle? • Is it possible—and desirable—to escape the cycle of repeated births and deaths? If so, how? • What awaits the soul aŌer liberation? Where does it go, and what does it do?
The Journey of the Soul
The Vedas: Sources of Wisdom
The most comprehensive sources on reincarnation are the Vedas, the sacred scriptures of India. Dating back approximately 5,000 years, they are considered the oldest known religious texts in human history. The word veda comes from Sanskrit—India’s ancient classical language—and means “knowledge.” The Vedas encompass wisdom across a vast range of fields, including Āyurveda (medicine), Jyotirveda (astronomy and astrology), Sthāpatya-veda (architecture and engineering), Gāndharva-veda (music and art), and Dhanur-veda (martial disciplines). Due to the complexity of Sanskrit, these scriptures remained largely inaccessible to the Western world for centuries. The first major translations appeared in the 19th century, when the German Indologist Max Müller (1823–1900) undertook the task of translating key Vedic texts into English and German. In more recent times, Śrīla A. C. Bhaktivedanta Swami Prabhupāda (1896–1977), Founder-Ācārya of the International Society for Krishna Consciousness, translated more than seventy volumes of these ancient Sanskrit texts into English. His translations and commentaries—now available in all major world languages—are recognized as standard reference works in many of the world’s universities and are widely used in academic courses on Indian philosophy and religion. Among the vast Vedic corpus, the most renowned texts are the Bhagavad-gītā (lit. “The Song of God”) and the Śrīmad-Bhāgavatam (lit. The Beautiful Story of the Supreme Person). The Gītā forms part of the monumental epic Mahābhārata, regarded as the longest literary work in world history, with over 100,000 verses. Though the Bhagavad-gītā consists of only 700 verses, it is the most celebrated of the Vedic scriptures, as it distills the essence of all fundamental aspects of Vedic wisdom. Presented as a dialogue between Kṛṣṇa, the
Supreme Person, and Arjuna, His friend and disciple, it addresses central themes such as the nature of the soul, the Supreme Soul, time, death, and reincarnation. For this reason, we will oŌen turn to this text to explain the process of the soul’s transmigration and other related topics.
The Mystery of Life
Modern science defines life as "a living organism composed of one or more cells that grow, develop, reproduce, respond to stimuli, and possess a metabolism." But what animates the cell to grow and develop? Dead cells, for instance, no longer grow or reproduce. What do they lack? If life is merely a complex chemical reaction, then why can we not supply the missing ingredients to a dead cell to restore its life? In 1966, English molecular biologist and Nobel laureate Francis Crick, who co-discovered the double-helix structure of DNA in 1953, proclaimed that science would soon be able to synthetically generate a living organism by combining amino acids. However, despite continuous atempts, highly advanced technology, and billion-dollar budgets, no one has been able to produce life in the laboratory–not then, not today. In fact, Śrīla Prabhupāda challenged the scientific community in 1973, saying that they would never be capable of producing life. He stated: "I do not even ask them to generate a human being, but only to produce something as simple as an ant or a blade of grass. But that is not possible, because life does not come from matter—life comes from life." The Bhagavad-gītā explains that living organisms show symptoms of life because they are animated by the vital force, which is, by constitution, an immaterial energy particle. In Sanskrit, this particle is named ātmā or jīva, identical to what is understood in the West as the soul. Although the jīva is found in a material body, it is extremely subtle. It is a spiritual substance, infinitesimal, and beyond the
The Journey of the Soul
perception of our senses. The Śvetāśvatāra Upaniṣad (5.9) gives a hint about the size of the soul: bālāgra-śata-bhāgasya śatadhā kalpitasya ca bhāgo jīvaḥ sa vijñeyaḥ sa cānantyāya kalpate “When the upper point of a hair is divided into one hundred parts and again each of such parts is further divided into one hundred parts, each such part is the measurement of the dimension of the spirit soul." Being of a different nature, the spiritual spark that animates the material body cannot be detected even with the most powerful microscope, nor is it imaginable through mental conjectures. In fact, science itself admits that life eludes scientific investigation and remains a mystery. The aforementioned Francis Crick recognized this perplexity in 1981 in his book Life Itself: "What we have discovered is that, even at this very fundamental level of proteins, complex structures exist. Of these, there are many identical reproductions, meaning they possess organized complexity and could not have been formed by pure chance. From this point of view, life is an infinitely rare occurrence; nevertheless, it proliferates around us. How can such rare things be common?" Just as light is the symptom of the Sun, consciousness is the symptom of the soul. We may not see the Sun because clouds obscure our view, but the light of day allows us to understand that the Sun is in the firmament, illuminating everything through its rays. Similarly, although we do not have the capacity to see the spiritual soul with our material eyes, we can deduce its presence from the presence of consciousness. Because the soul belongs to the immaterial dimension, its qualities and characteristics cannot be observed even through the most advanced material technology. The Danish physicist and Nobel laureate Niels Bohr (1885-1962) recognized: "We must admit that we cannot find anything in physics or chemistry that bears even a remote relationship to consciousness. However, we know that consciousness exists, because the simple fact is that we ourselves possess it. Consequently, consciousness must be a part of nature, or rather, a part of reality. But that means we must suppose that, apart from the physical and chemical laws explained by quantum theory, other laws of a completely different nature exist."
The Gross Body and the Subtle Body
The spiritual soul develops material bodies corresponding to its level of consciousness, which in turn evolves and changes through the soul's interaction with the body and its surroundings. The material body is composed of two main parts: the gross body and the subtle body. Kṛṣṇa explains in the Bhagavad-gītā (7.4) that material nature comprises eight basic elements—five gross and three subtle—which provide the ingredients for the formation of the two bodies:
1. earth
2. water
3. fire
4. air
5. ether
6. mind
7. intelligence
8. ego
The Journey of the Soul
In modern scientific terminology, the five gross elements correspond to all forms of solid matter (earth), liquids (water), radiant energy (fire), gases (air), and omnipresent space (ether). All phenomena we perceive in this world consist of a combination of these five primary elements. Our eyes see forms, our ears perceive sounds, our nose smells odors, our tongue tastes flavors, and our skin perceives structures. Thus, we, the jīvas, interact with the external world through the senses of the gross body. The three subtle elements—mind, intelligence, and ego—cannot be seen, heard, smelled, tasted, or touched. Nevertheless, we know they exist because their symptoms are perceptible. The mind's presence is evident through its faculties of thinking, feeling, and willing. Intelligence manifests as the faculty of discrimination, and ego is revealed through the sense of identity each of us possesses. Because this identity is oŌen linked to the temporary material body, this sense of ego is termed ahankara, or false ego, in Sanskrit, as our true identity is spiritual in nature. We will delve deeper into this topic latter.
The Spiritual Spark
Let us now examine the characteristics of the spiritual soul. AŌer enumerating the eight material elements and classifying them as apara-prakṛti, inferior energy, Kṛṣṇa further explains (Bg. 7.5) : "Apart from this inferior energy, there is another superior energy, parāprakṛti, the living entities who utilize the resources of the universe." The spiritual soul is superior to matter and possesses the power to manipulate and utilize it to fulfill its desires. The jīva's interaction with its gross and subtle bodies results in an extremely complex network of reactions, one that extends beyond the scope of physics, chemistry, and nuclear biology. This is precisely why science finds it so difficult to define the exact difference between a living and a dead body. Something is clearly missing, but its precise nature remains unknown. The Bhagavad-gītā defines the difference between a living and a dead body by the presence or absence of the soul. As soon as the jīva departs from the body, it is considered "dead." The characteristics of the jīva are explained in detail in the Second Chapter of the Bhagavad-gītā (Verses 20, 23-24): "For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal, ever-existing and primeval. He is not slain when the body is slain. "The soul can never be cut to pieces by any weapon, nor burned by fire, nor moistened by water, nor withered by the wind. "This individual soul is unbreakable and insoluble, and can be neither burned nor dried. He is everlasting, present everywhere, unchangeable, immovable and eternally the same." The question may arise, if the soul is eternally the same, how do the different species of life appear? The Bhagavad-gītā (13.22) explains this is due to the soul's contact with the material qualities or modes,the guṇas: kāraṇaṁ guṇa-saṅgo 'sya sad-asad-yoni-janmasu. The translation states: "Due to its contact with material nature, the living entity encounters good and bad in the different species."
The Three Modes (guṇas)
According to Vedic natural sciences, the variety of species arises from the combination and gradation of three fundamental modes of material energy: 1. sattva-guṇa (goodness),
The Journey of the Soul
2. raja-guṇa (passion), and 3. tama-guṇa (ignorance). The three guṇas can be compared to the three primary colors— yellow, red, and blue—which form the basis for a vast variety of shades. If we mix the three primary colors, we obtain six secondary colors, then six tertiary, and so on. Similarly, the three modes of nature can form numerous combinations, giving rise to bodies and mentalities that align with every imaginable type of consciousness. Scientific discoveries regarding DNA structure support this view, as it has been shown that each DNA is unique, allowing individual identification through DNA analysis. The various bodies of living entities can be compared to different types of vehicles or houses, each distinct in size, shape, and color. The soul, as the inhabitant of each body, is conditioned by the three guṇas that largely determine its freedom of movement and action, its potential for enjoyment, and its capacity to manipulate the environment. A tree, for example, is immobile; a turtle moves very slowly, while a horse can run and jump freely. There is an immense variety of living beings, each with unique peculiarities and differences shaped by the three guṇas. Although the modality of ignorance predominates in plants and animals, gradations exist even within these species. Among animals, the donkey typically embodies ignorance, the tiger and other predators symbolize passion, while the cow and bee, which only work for the benefit of others, exemplify goodness. Even within the same species, we find such differences. Among birds, the swan symbolizes goodness, the eagle passion, and the crow ignorance. While a biological similarity exists among representatives of the same species, the consciousness and actions of different beings show distinct expressions resulting from the influence of the modes of nature.
Human beings are no exception. People primarily influenced by goodness display qualities such as compassion, honesty, charity, and loyalty. Those acting primarily under passion are dominated by selfishness, envy, greed, lust, a desire for power, and a craving for fame. In others, whose life is dominated by ignorance, inertia, foolishness, and regular states of intoxication are prominent. Thus, a great variety of material bodies exist, where the living entity can take its seat to play its role in accordance with the three guṇas that influence its consciousness. The three guṇas are also compared to three types of ropes that bind the soul to material existence. As consciousness remains absorbed in their qualities, the soul is dragged from one material body to another. The process of bhakti-yoga, which we will explain in the last chapter, aims to end this miserable situation, overcome the three guṇas, and connect consciousness with Transcendence. Kṛṣṇa says in the Bhagavad-gītā (14.26): māṁ ca yo ’vyabhicāreṇa bhakti-yogena sevate sa guṇān samatītyaitān brahma-bhūyāya kalpate "Aquel que se dedica por completo al bhakti-yoga [servicio devocional], firme en todas las circunstancias, transciende de inmediato las modalidades de la naturaleza y llega así al plano del Brahman [la Trascendencia]." We will latter discuss the transcendental plane, Transcendence, and its different aspects in depth.
The Change of Body in the Present Life
If we observe our own existence, we realize our body has changed in many ways since birth. Even so, we feel like the same person. We remember our youth and recognize ourselves in photos, even though our body is now different, our mindset has changed, and our feelings are not the same. This transmigration of the soul through a single
The Journey of the Soul
body during a single life could be described as "internal reincarnation." Building on this universal human experience, the Bhagavad-gītā (2.13) offers a key analogy to explain reincarnation: "Just as in the present body the embodied soul passes from childhood to youth and then to old age, in the same way the soul passes to another body at the moment of death."
The Change of Body at the Moment of Death
With this analogy, Kṛṣṇa establishes the foundation of spiritual knowledge. The first lesson consists of understanding the difference between matter and spirit. Ahaṁ brahmāsmi, 'I am spiritual soul,' is the primordial and essential realization for a transcendentalist. Kṛṣṇa also answers the question: 'What determines one's future life, and what does the type of body one receives aŌer death depend on?' In Chapter Eight, Verse 6, he says: "Whatever state of existence a person remembers when he leaves the body, that state he will attain without fail." And latter (Bg. 15.8): "The living entity in the material world carries from one body to another its different conceptions of life, just as the air carries aromas. Thus, it adopts one type of body, and again leaves it to adopt another." The Vedic scriptures provide a metaphysical explanation of life’s continuity beyond death, but are there any indications from contemporary experience that support this view? One compelling body of evidence comes from the growing number of welldocumented near-death experiences.
Glimpses Beyond Death:
Near-Death Experiences
While traditional spiritual texts like the Bhagavad-gītā speak authoritatively about the soul’s existence beyond the body, modern research into near-death experiences (NDEs) offers intriguing support from another angle. NDEs occur when individuals are clinically dead or in a state of extreme physiological shutdown—yet report vivid, structured experiences during that time, oŌen including out-of-body perception, encounters with light or beings, panoramic life reviews, and a profound sense of peace or purpose. In many well-documented cases, patients have described events and conversations that occurred in the operating room or elsewhere while their brain activity was flatlined and they were medically unresponsive. These accounts have been carefully studied by researchers like Dr. Raymond Moody, Dr. Bruce Greyson, and Dr. Pim van Lommel, among others. In controlled clinical seƫngs, numerous reports of accurate out-of-body observations challenge the notion that consciousness is simply a byproduct of brain function. One of the most striking paterns in NDEs is the consistent affirmation of personal identity and conscious awareness, even when all biological signs of life have ceased. These accounts resonate strongly with the Vedic understanding that the self—the jīva—is not dependent on the physical body for its existence, and that death is not extinction, but transition. Although such experiences vary culturally in their expression, the core elements are remarkably universal. Many return with transformed lives, renewed purpose, and a diminished fear of death. This psychological and spiritual aŌer-effect points not only to the reality of the soul’s continuity, but also to the possibility that consciousness is non-local—not bound by the brain or nervous system. While skeptics may dismiss NDEs as hallucinations or mere neurological phenomena, no purely material explanation has been able to fully account for the clarity, coherence, and accuracy of many such reports. When considered alongside scriptural testimony and philosophical reasoning, near-death experiences offer a powerful
The Journey of the Soul
modern echo of what the Vedas have taught for millennia: that life does not end with the death of the body, and that our true identity lies beyond the reach of flesh and bone. These experiences, however, represent only a brief crossing of the threshold—moments when the soul hovers near departure but ultimately returns to the same body. But what happens when death is final? When the soul fully leaves the body and enters another? Here we enter a deeper dimension of the soul’s journey. In recent decades, thousands of documented cases—especially among young children—have given further weight to the idea that consciousness not only survives death, but carries with it impressions and memories from previous lifetimes.
Memories of Past Lives
When the topic of reincarnation arises, one of the most common questions is: If we’ve lived before, why don’t we remember? At first glance, this seems like a strong objection—but even within our current lifetime, memory is far from perfect. We oŌen forget what we were doing just a few days ago, let alone events from early childhood. Memory fades, fragments, and sometimes disappears entirely. Moreover, imagine if we could remember not just this life in full detail, but also countless lives before it. Such overwhelming recollection could easily destabilize the mind. The human psyche, as it is, is not equipped to bear that weight. From this perspective, the veil of forgeƞulness may be understood not as a flaw, but as a form of protection—or even compassion. As Kṛṣṇa states in the Bhagavadgītā (15.15): sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca—“I am seated in the heart of everyone, and from Me come remembrance, knowledge, and forgeƞulness.” Despite this natural forgeƞulness, there are well-documented cases—especially among very young children—who report vivid and detailed memories of previous lives. These accounts oŌen include names, places, relationships, and even circumstances of death, many of which have been verified through investigation. One of the most respected researchers in this field was Dr. Ian Stevenson, a psychiatrist at the University of Virginia, who spent over four decades studying thousands of such cases across cultures and continents. His meticulous documentation focused on children who, between the ages of two and seven, spontaneously recalled past-life experiences. Many of these children displayed knowledge of people, events, and locations that were geographically and culturally distant from their current families. In some cases, they even bore birthmarks or physical traits corresponding to injuries or wounds from the life they claimed to remember. Stevenson’s successor, Dr. Jim Tucker, has continued this work and published several studies and accessible summaries, confirming that these phenomena are neither rare nor culturally isolated. Although modern science has yet to explain these memories within a materialist framework, the phenomenon aligns closely with the Vedic teaching that the soul (jīva) carries not only karma but subtle impressions (saṁskāras) from one life to the next. Thus, the ability to forget may itself be seen as an act of divine grace—allowing us to live in the present without the burden of unresolved memories. Nevertheless, those who wish to learn about their past lives sometimes turn to techniques such as past-life regression therapy, which claim to retrieve buried memories from previous incarnations. But is this truly necessary? The past does not return and cannot be changed. What we can and should change is the present—thereby shaping our future. At the moment of death, the jīva leaves the gross body, carried by the subtle body. This subtle body, containing the soul’s thoughts,
The Journey of the Soul
feelings, and desires, largely determines the nature of the next gross body. Yet these inner impressions are not the sole factor shaping our future. Another force also plays a decisive role.
