What we call 'I' is just a swinging door which moves when we inhale and when we exhale. It just moves; that is all. When your mind is pure and calm enough to follow this movement, there is nothing: no 'I,' no world, no mind nor body; just a swinging door.
When you do something, you should burn yourself completely, like a good bonfire, leaving no trace of yourself.
There are, strictly speaking, no enlightened people, there is only enlightened activity.
