empty yourself
Philosophy has many questions, many answers -- millions. Religion has only one answer; whatsoever the question the answer remains the same. Buddha used to say: You taste sea water from anywhere, the taste remains the same, the saltiness of it.
Whatsoever you ask is really irrelevant.
One answer is like a master key; it opens all doors. It is not concerned with any particular lock -- any lock and the key opens it. Religion has only one answer and that answer is meditation. And meditation means how to empty yourself.
