There is nothing called spiritual knowledge || Acharya Prashant, on Ishavasya Upanishad (2016)

Different indeed, they say, is the result of vidya and different indeed, they say, is the result of avidya. Thus have we heard from the wise who had explained it to us. He who knows both vidya and avidya together, transcends mortality through avidya and reaches immortality through vidya.

~ Ishavasya Upanishad, Verse 10 and 11 ~

Acharya Prashant: One thing, they say, is obtained from vidya. Another, they say, from avidya. Thus, we have heard from the wise who have taught us this. ‛He who is aware that both vidya and avidya should be pursued together overcomes death through ignorance, which is avidya; overcomes death through avidya. And obtains immortality through vidya.’

The text here has used the word ‘avidya’ for ignorance, which is quite not proper. What is this whole business of vidya and avidya? What does that have to do with overcoming death and obtaining immortality

Knowledge is knowledge. Be it any kind of knowledge, it is just knowledge. But the human mind has a tendency to look at everything in a divided way. Anything, any object that exists in the mind is necessarily limited and hence, divided. Divided from the rest of existence. One fundamental distinction that exists in the mind is the distinction between the Universe and the self. That is what is also called as the ego — ‘I am’. ‘I am’ separate from the universe.
