All of asta wakr is basically saying one thing about our reality, which is already present. Astavakra's words should be taken as a pointer, not so much as an argument,. It's trying to show us something. At any time if you feel like closing your eyes and focusing on what he's trying to point out, that's wonderful. Any time if youfeel it is an exercise in meditation, astavakr is actually an exercise in non dual meditation.
