Gyana yoga is cleanup, not new knowledge

The whole, if there is a point, the whole point of Ganeva teaching or scripture is to do the cleanup not for a new, not for a construction of new knowledge, but to come to this innocent self-knowledge which is ever present by moving the nonsense we have seems to obscure it. And all the nonsense are centered around the non-existent one. You need to simply that like this and I like that. I like, I do, I don't like, I don't do. What is suffering?
