“On what is the body supported?” asks Sakalya. “On the life breath
    and its five forms – in-breath, out-breath, diffused-breath, equalizing-breath,
    and ascending-breath. This life-breath, prana, is identical with Self.
    Yajnavalkya then describes Self. It is imperceptible because it is never perceived,
    indestructible because it is never destroyed, unattached because it does not attach
    itself and unfettered because it does not suffer. It is beyond suffering and injury.
    It is described as ‘neti, neti’, not this, not this. Whatever
    Sakalya talked about were only about the abodes, worlds, gods and beings of the
    Self, the Cosmic Person, Purusha.
    Next, Yajnavalkya takes the floor and asks a question to Sakalya: “Who is
    that Cosmic Person, Purusha taught in the Upanishads?” He also announces that
    if Sakalya is unable to explain this to him, his head will fall off. Sakalya could
    not answer and his head fell off. Moreover robbers took even that fallen head away
    thinking that it was something else.
    In conclusion, Yajnavalkya invited questions from the audience and also suggested
    that he might put questions to the members of the audience. The assembled Brahmins
    could not dare to say anything to Yajnavalkya. Then Yajnavalskya asked them a question
    as in the following mantra.(3.9.28)
    “As is a mighty tree, so, indeed is a man. His hairs are like leaves and his
    skin like the outer bark of a tree. From his skin blood flows forth, like sap from
    the skin of a tree. Therefore, when a man is wounded, blood flows like sap from
    a tree that is struck. His flesh is its inner bark; his nerves are tough like inner
    fibers. His bones are the woods within and marrow resembles the pith. A tree when
    it is felled springs up from its roots in a newer form. From what root does man
    spring forth when he is cutoff by death?
    Do not say ‘from procreative fluid’, since that is produced only from
    a living man. A tree springs also from the seed after it is felled. But if a tree
    is pulled out with its roots and seeds it will not spring again. But a man is born
    after death, even though his body is completely destroyed. So, who causes his rebirth?
    From what root does a mortal spring forth when he is cut off by death?
    If you say ‘he is never born, I say ‘no’. He is born again after
    death. Who creates him again?
    It is Brahman. He is knowledge and Bliss. He is the final goal of him who offers
    charities as well as of him who stands firm and knows Brahman”.
    This is an oft-quoted mantra. After the similarities between a man and a tree are
    shown, the dissimilarities are pointed out. The issue raised by Yajnavalkya in this
    last mantra of the section relates to the concept of rebirth or transmigration of
    the soul after death of man which is based on the law of karma.
    The naturalists (svabhava vadins) believe that a man is born naturally.
    They don’t believe in any other cause apart from nature. Everything is mechanical
    for them like materialists. For them a man is a naturally born product and he would
    not be born again after death. Their theory is that the universe is produced and
    is sustained by the natural and necessary action of substances according to their
    inherent properties and not by the agency of a Supreme Conscious Being. But Yajnavalkya
    does not agree to this line of thought.
    According to Yajnavalkya, the soul is immortal; a man had previous lives and he
    will have future lives also after his death. If rebirth governed by the law of karma
    is not accepted, then a man must reap the fruit of action he has never done and
    does not have to accept the fruit of action which he has already done. This would
    obviously nullify the law of cause and effect. Then how doe we explain man’s
    present state? Therefore the theory of karma and rebirth is the only theory
    that explains the difference between man and man. Each man is what he has made him
    in the course of his numerous past lives.
    Further, the doctrine of rebirth is a necessary corollary of the doctrine of the
    immortality of the soul. That is why Yajnavalkya asked who is the cause of a man’s
    being born again. The Vedic scholars did not know the answer. They did not know
    Brahman, the ultimate root of the universe, which is responsible for rebirth and
    the other phenomena of the relative universe. But Yajnavalkya knew Brahman. Thus
    he defeated the Brahmins and took away the cows.
    The story is finished and the Upanishad describes the root of the universe in words
    which directly apply to Brahman. It says Brahman is Knowledge (pure intelligence
    free from the duality of knower and the object of knowledge) and Bliss (unlike the
    happiness caused by the sensory perceptions, this Bliss, which is the same as Knowledge
    is not stained by pain) – vijnanam anandam brahma. Brahman is vijnanam
    and anandam, Consciousness and Bliss. That is the wonderful teaching of
    this section.
    CONCLUSION
    Thus the basic thought of this section is that Brahman (Atman, the Upanishadic Purusha)
    is the ultimate unity to which the Vedic Gods, the vital power in man, the guardian
    deities in man and man himself are all traced back.
