"There are two fundamental cosmic truths: sound and non-sound. The inner sound only receives manifestation in the outer sound. This is therefore the way."
"When [in the world] one sees nothing else, hears nothing else, recognizes nothing else: that is [participation in] the Infinite. But when one sees, hears, and recognizes only otherness: that is smallness. The Infinite is the immortal. That which is small is mortal."
"That [which is beyond every name and form] is comprehended only by the one with no comprehension of it: anyone comprehending, knows it not. Unknown to the knowing, it is the unknowing known."
"When you see that God acts through you at every moment, in every movement of mind or body, you attain true freedom. When you realize the truth, and cling to nothing in the world, you enter eternal life."
"There is a bridge between time and eternity; and this bridge is Atman, the spirit of man. Neither day nor night cross that bridge, nor old age, nor death, nor sorrow. It is this spirit that we must find and know: man must find his own soul. He who has found and knows his soul has found all the worlds, has achieved all his desires."

So the aim is to realize the brahman, the ultimate reality. - Nirvana Upanishad"

"The Spirit, without moving, is swifter than the mind; the senses cannot reach him: He is ever beyond them. Standing still, he overtakes those who run. To the ocean of his being, the spirit of life leads the streams of action. He moves, and he moves not. He is far, and he is near. He is within all, and he is outside all. Who sees all beings in his own Self, and his own Self in all beings, loses all fear. When a sage sees this great Unity and his Self has become all beings, what delusion and what sorrow can ever be near him? The Spirit filled all with his radiance. He is incorporeal and invulnerable, pure and untouched by evil. He is the supreme seer and thinker, immanent and transcendent. He places all things in the path of Eternity. Into deep darkness fall those who follow action. Into deeper darkness fall those who follow knowledge. One is the outcome of knowledge, and another is the outcome of action. Thus have we heard from the ancient sages who explained this truth to us. He who knows both knowledge and action, with action overcomes death and with knowledge reaches immortality. Into deeper darkness fall those who follow the immanent. Into deeper darkness fall those who follow the transcendent. One is the outcome of the transcendent, and another is the outcome of the immanent. Thus have we heard from the ancient sages who explained this truth to us. He who knows both the transcendent and the immanent, with the immanent overcomes death and with the transcendent reaches immortality. – Isa Upanishad"
