Do the Vedas really contain any advanced knowledge as so many people claim they do?    QUORA

15.3.15 – I’d say the Vedas contain the most fundamental and ‘advanced’ knowledge there is, though mostly portrayed  in the form of paradox (analogy, metaphor, story, etc.), so that one has to crack the code in order to find the wealth hidden in them. That knowledge is not like empirical science, which is cumulative and provisional, and which could be said to be somehow contained in it, even if in embryonic or potential form. That knowledge or perspective is metaphysical rather than mystical. According to the Vedas there is one and only one reality: consciousness (brahman, the Absolute, etc.), which pervades the whole universe; it is immanent in it as well as transcendent… “the smallest of the small, the largest of the large”. It cannot be measured out or understood by the mind, for which it is ineffable, but it is that by which the mind comprehends… it cannot be expressed in words but by which the tongue speaks… it is eye of the eye, ear of the ear, mind of the mind, as expressed in the Upanishads.

Modern physics is having a hard time trying to explain away what consciousness is in terms of physical phenomena (neuronal activity in the brain), but consciousness is not just an irreducible phenomenon or datum; it is reality itself, everything being comprehended in it (theories, doubts, projections, emotions, things, thoughts, intelligence, observer and observed, you and I). The part (for instance, an ‘external’ observer) cannot understand the whole into which he/she is enclosed. For the Vedas, to repeat, reality is one, and contemporary physics is trying to find out in which way it is so (‘theory of everything’, ‘unified field’…). Not all physicists are reductionist, some of them having seemingly mutated into philosophers with a workable understanding of the core of Vedic teachings.
