7—9) "As the various particular kinds of notes of a drum, when it is beaten, 
    cannot be grasped by themselves, but are grasped only when the general note of 
    the drum or the general sound produced by different kinds of strokes is grasped; 
    "And as the various particular notes of a conch, when it is blown, cannot be 
    grasped by themselves, but are grasped only when the general note of the conch 
    or the general sound produced by different kinds of blowing is grasped; "And as 
    the various particular notes of a vina, when it is played, cannot be grasped by 
    themselves, but are grasped Only when the general note of the vina or the 
    general sound produced by different kinds of playing is grasped; Similarly, no 
    particular objects are perceived in the waking and dream states apart from Pure 
    Intelligence.
    By these three illustrations, sage Yajnavalkya tells us that the effect cannot 
    be known unless the cause is known, because the effect is a manifestation of the 
    cause in some proportion. We cannot understand the nature of any object in this 
    world unless we know wherefrom it has come. Unless the cause behind the form 
    that is visible is perceived, the form cannot be really known or understood.
    If we are intent upon knowing the nature of any object, we must know its 
    relation to something else. And that something else is connected to another 
    thing, and so on and so on, until we will be surprised to realize that 
    everything is connected to everything else in such a way that nothing can be 
    known unless everything is known. So, it is not possible to have complete 
    knowledge of any finite object unless the Infinite itself is known.
    To understand this, the great Master Yajnavalkya gives us three illustrations. 
    Just as the sound that is made by a percussion instrument cannot be properly 
    identified if the instrument itself is far away and not visible to the eyes, but 
    whose sound is heard by us from a distance, unless we catch the source thereof; 
    just as we cannot identify the rhythm produced by the blowing of a conch unless 
    we have the capacity to grasp the totality of the sound by actually perceiving 
    the conch that is being blown at any particular time; just as we cannot 
    understand the symphony produced by a Veena or a stringed instrument, for 
    instance, merely by hearing one note unless we are able to connect all the notes 
    in a harmonious symphony, so is the case with all these things in this world. 
    The particular notes or tunes from a musical instrument are modifications of the 
    general note emanating from it; they cannot be perceived because they have no 
    existence apart from the general note.
    All things in the universe are each like one note in the symphony. How can we 
    know the beauty of the music by merely hearing one note? That note is connected 
    to many other notes. And when every note is harmoniously related to all other 
    notes to which it is related, and all the notes are grasped at one stroke in one 
    single harmonious symphony, that becomes music; it is melodious. But if only a 
    twang is heard or one tick is heard, it makes no sense; it is not music.
    So is the case with any object in this world. It is one twang, one tick, one 
    sound which is really connected to a vast arena of a symphony that is 
    universally expansive. Unless that total expanse or continuity is grasped by the 
    mind at one stroke, which means that unless the infinite Being behind the finite 
    objects is grasped by the consciousness, no finite object can be known fully, 
    nothing can be understood perfectly. Therefore, nothing can give us 
    satisfaction. During the continuance of the universe, all diverse entities are 
    unified in Brahman or Pure Intelligence, because the varieties or diversities 
    are not different from It. Thus there is no hope of immortality through any 
    possession in this world, is the conclusion of Sage Yajnavalkya.
    What Yajnavalkya says is that the nature of effects cannot be known unless their 
    cause is known. It is futile on our part to investigate into the nature of any 
    finite object without correlating its form and context with the causes which 
    gave rise to its present form.
    But, the incapacity of the senses to perceive the causes behind the visible 
    forms creates a false impression in the mind that the causes are completely 
    isolated from the existence of the effect. This is why we make independent 
    notional judgments about things, distancing them from the conditions from which 
    they are evolved, which are ultimately cosmic conditions. The point made out in 
    the Upanishad, in this passage, is that without the knowledge of the Absolute, 
    not even the smallest of things can be understood and that nothing exists apart 
    from Brahman, Pure Intelligence.
    10) "As from a fire kindled with wet fuel various kinds of smoke issue forth, 
    even so, my dear, the Rig Veda, the Yajur Veda, the Sama Veda, the 
    Atharvangirasa, history (itihasa), mythology (purana), the arts (vidya), the 
    Upanishads, verses (slokas), aphorisms (sutras), elucidations (anuvyakhyanas) 
    and explanations (vyakhyanas) are like the breath of this infinite Reality. From 
    this Supreme Self are all these, indeed, breathed forth.
    Now, this passage tells us that everything proceeds from that Pure Intelligence, 
    the Absolute. How does it come?
    We cannot understand how anything can come from the Absolute. We can only give 
    some illustrations, and the Upanishad employs here the comparison of smoke 
    arising from fire. Just as when wet fuel is burnt smoke may arise from 
    its burning process, everything may be said to proceed in this manner, as it 
    were, from the Supreme Being - a continuous emanation. As before the separation 
    of the sparks, embers, and flames, all these are nothing but fire and therefore 
    there is but one substance, fire, so too, this universe before it differentiated 
    itself into names and forms, is nothing but Pure Intelligence.
    Evam va are asya mahato bhutasya nihsvasitam: From the breathing, as it 
    were, of this eternal, infinite Reality, all the knowledge of this world has 
    come. Just as when you breathe out there is a breath coming from your nostrils, 
    the Absolute breathes, as it were, this wisdom of all His creation. And, all 
    this wisdom of the world put together cannot be equated with a fraction of It.
    The wisdom of the Vedas and everything that is capable of being connected with 
    Vedic knowledge, such as the Itihasas, Puranas, Vidya, all arts and all branches 
    of learning, secret teachings, verses and poetic compositions, aphorisms, 
    commentaries, anything that can be called knowledge, in whatever way, whatever 
    manner, whatever form, everything has come out from Brahman as a man’s breath 
    comes out without any effort.
    11) "As the ocean is the one goal of all waters (i.e. the place where they 
    merge), so the skin is the one goal of all kinds of touch, the nostrils are the 
    one goal of all smells, the tongue is the one goal of all tastes, the ear is the 
    one goal of all sounds, the mind is the one goal of all deliberations, the 
    intellect is the one goal of all forms of knowledge, the hands are the one goal 
    of all actions, the organ of generation is the one goal of all kinds of 
    enjoyment, the excretory organ is the one goal of all excretions, the feet are 
    the one goal of all kinds of walking, the organ of speech is the one goal of all 
    the Vedas.
    The ocean is the repository of all waters on the earth. The touch-sense 
    and everything that we regard as meaningful from the point of view of 
    tangibility is located in the skin. Every kind of taste can be located 
    ultimately in the structural pattern of the tongue, or the palate. Every
    smell, every odor, every type of fragrance is located in the structure of 
    the nostrils. Every color, every form, everything that is visible, 
    is located in the structure of the eyes. Every sound, whatever it is, is 
    located in the structure of the ears. Every thought, every 
    feeling, anything that is cogitated is ultimately located in the mind. 
    Every feeling, every kind of intimation, connected with the knowledge of things, 
    is in the heart of a person. Every action, the capacity to grasp things, is 
    located in the energy of the hands of a person.
    Other organs also are mentioned in this manner, making out that all activities 
    of the senses are capable of being traced back to the structure of the senses, 
    so that if we know the nature of the sense-organs concerned in any particular 
    action, whether it is the action of knowledge or merely of locomotion, enjoyment 
    etc., we can know everything connected with that particular organ. Likewise, we 
    can know all things if we can locate their origin, from where they proceed.
    All these different examples signify the idea of one common goal, one common 
    centre where all merge. Similarly the whole universe is ultimately centered in 
    this one Reality which is the source of all.
    12) "As a lump of salt dropped into water becomes dissolved in water and 
    cannot be taken out again, but wherever we taste the water it tastes salt, even 
    so, my dear, this great, endless, infinite Reality is Pure Intelligence alone. 
    This self comes out as a separate entity from these elements and with their 
    destruction this separate existence also is destroyed. After attaining oneness 
    it has no more consciousness. This is what I say, my dear." So said Yajnavalkya.
    Another illustration is given here to make out the nature of the Supreme Being 
    from whom all knowledge proceeds. If we dissolve a little piece of salt in 
    water, what happens? The salt becomes one with the water. We may take any part 
    of that water, it will taste salty, and we cannot find out where the salt is. It 
    has become one with the water; it is everywhere in the water.
    Just as any part of that water in which salt is dissolved will taste of salt 
    only, because of the pervasive character of the salt that has got dissolved into 
    the water, so is the Infinite Being. How? It is a mass of knowledge; it is a 
    treasure house of wisdom; it is a substantiality of what we regard as the 
    highest Consciousness; that is this ultimate Reality. Wherever we touch, it is 
    that which is touched, and wherever we taste we are tasting that only, and 
    anything that is seen anywhere is naturally that only. Whatever be the 
    corresponding object of a particular sense-organ, it is the form of That which 
    is seen. And the mind thinks nothing but That, not knowing it is so doing.
    This consciousness which is solid Reality ultimately, the substantiality of the 
    whole universe, appears to localize itself in the body of individuals by 
    entering into the process of permutation and combination of the elements like  
    earth, water, fire, air, ether, etc. A particular combination in some percentage 
    of these five elements becomes a body, an embodiment. When consciousness enters 
    this particular formation of the elements, it is what we call the individual, 
    the Jiva, or a particular finite body. It arises in this form and dissolves 
    itself in this form, as it were, as long as it is connected to this formation of 
    the elements.
    The birth of the individual and the death of the individual are described here, 
    as being the consequence of the association and dissolution of consciousness 
    within the formation of the five elements in a certain proportion. It is the 
    five elements which combine in certain ways and conditions that are responsible 
    for the objects of sense, as we call them.
    Animate or inanimate, whatever may be - all the objects, all the bodies are 
    really the elements in some shape, color and tangibility. They appear to have a 
    value, a worth, and meaning, because of the entry of consciousness into them. 
    And when the formations change, when there is a different type of formation of 
    the elements that is called the death of the individual.
    It is not a death really; it is a transformation, a reformation of the 
    particular form into which these elements have been cast by the need of that 
    unit of consciousness which is called the Jiva. When this consciousness gets 
    entangled in the forms of the elements, it is called birth. When it is freed 
    from them, it is called death. When it is freed from the elements, it will not 
    be conscious of any particular thing.
    Yajnavalkya tells Maitreyi that when there is total isolation of consciousness 
    from all its associations in the form of these permutations and combinations of 
    elements called the body, there would be no particular consciousness. There 
    would be no feeling, hearing, touching, smelling, - nothing particular 
    whatsoever, no consciousness at all. So says Yajnavalkya, "after dissolution, 
    there is no awareness". This is what is meant by this pithy statement - na 
    pretya samjnasti. "Maitreyi; this I tell you. Try to understand it."
