Is the Ashtavakra Gita the deepest of all of 'though' because it rejects existence & thought itself ?

From the Ashtavakra Gita: 16.1 You can recite and discuss scripture all you want, but until you are willing to forget everything, you will never know Truth. 16.4 The master idler, to whom even blinking is a bother, is happy. But he is the only one. 17.7 The man of Knowledge neither cares for the universe nor desires its dissolution. He lives happily on whatever comes his way. He is blessed. **\* I don't know a single human who has rejected existence itself to a point where they don't bother to even discuss it, let alone believe it matters. The irony of this post is by writing it, I actually am rejecting Ashtavakra's advice because I believe I exist and that his Gita exists, and that you the reader exists. The essence of his claim is that thought, thinking, desire, wanting this, hating that, etc .... is all an illusion, and that there is no such thing as "I" or "self". Even the contemplation of consciousness and thought is an illusion and that at the purest we are Awareness itself.**
