The Upanishads are Vedanta, a book of knowledge in a higher degree even than the Vedas, but knowledge in the profounder Indian sense of the word, JnanaJnana. And because it is only by an integral knowing of the self that this kind of direct knowledge can be made complete, it was the self of the Vedantic sages sought to know, to live in and to be one with it by identity. And through this endeavour they came easily to se that the self in us is one with the Universal Self of all things and that this self again is the same as God and Brahman, a transcendent Being or Existence, and they beheld, felt, lived in the inmost truth of manīs inner and outer existence by the light of this one and unifying vision. The Upanishads are epic hymns of self-knowledge and world-knowledge and God-knowledge.
This is only an excerpt from the insightfull Introduction to Sri Aurobindos own collection of Upanishad translations with magnificant commentaries that describe Aurobindos mission with the path of Integral Yoga. A Yoga which he describes as a corollary to the western gnostic observations and path of contemplation. In which I absolutely agree are close to the truth. I suggest a reading of the Corpus Hermeticuum and the Unpanishads as a way to come to grips how alike these paths are, I am not saying they are one, but I suggest that the wisdom that has arosen in the midst of the Rsiīs (seers) in India bears an baffling resemblance. Therefore I service those interested in the message and content of the gnostic orientation, with these translations.
