Concentration comes not from trying hard to focus on something, but from keeping your mind open and directing it at nothing.
Shunryu SuzukiDon't move. Just die over and over. Don't anticipate. Nothing can save you now because you have only this moment. Not even enlightenment will help you now because there are no other moments. With no future, be true to yourself and express yourself fully. Don't move.
Shunryu SuzukiIf you were not born in this world, there would be no need to die. To be born in this world is to die, to disappear [laughing].
