What is this Self? We have seen that It is even beyond the intellect. We learn from the same Upanishad that this Self is eternal and omnipresent, that you and I and all of us are omnipresent beings, and that the Self is changeless. Now this omnipresent Being can be only one. There cannot be two beings who are equally omnipresent — how could that be? There cannot be two beings who are infinite, and the result is, there is really only one Self, and you, I, and the whole universe are but one, appearing as many.
“As the one fire entering into the world manifests itself in various ways, even so that one Self, the Self of all, manifests Itself in every form.” But the question is: If this Self is perfect and pure, and the One Being of the universe, what becomes of It when It goes into the impure body, the wicked body, the good body, and so on? How can It remain perfect? “The one sun is the cause of vision in every eye, yet it is not touched by the defects in the eyes of any.” If a man has jaundice he sees everything as yellow; the cause of his vision is the sun, but his seeing everything as yellow does not touch the sun. Even so this One Being, though the Self of every one, is not touched by the purities or impurities outside. “In this world where everything is evanescent, he who knows Him who never changes, in this world of insentience, he who knows the one sentient Being, in this world of many, he who knows this One and sees Him in his own soul, unto him belongs eternal bliss, to none else, to none else.
There the sun shines not, nor the stars, nor the lightning flashes, what to speak of fire? He shining, everything shines; through His light everything becomes effulgent. When all the desires that trouble the heart cease, then the mortal becomes immortal, and here one attains Brahman. When all the crookedness of the heart disappears, when all its knots are cut asunder, then alone the mortal becomes immortal. This is the way. May this study bless us; may it maintain us; may it give us strength, may it become energy in us; may we not hate each other; peace unto all!” (II, 411- 412)
Which other culture or religion can claim a better universal and unifying vision? It is this Vedic Vision that has sustained the dynamism and relevance of our spiritual heritage. It is this vision that has been handed over from generation to generation through the uniquely Indian Guru Shishya Tradition and has provided the unique fragrance to the Indian culture which is sought out by the discerning people all over the world.
Every Hindu born in this Punyabhumi, in spite of his being ignorant of the great Hindu traditions, is aware of at least one thing, that is, within him lies the imperishable Atman which is one with everything in the universe.
