Dogen

Before I explain Dogen to you, let this be the introduction, because this is what he is trying to say: that everything passes and yet there is something that never passes; that everything is born and dies and yet there is something that is never born and never dies. And unless you get centered into that eternal source you will not find peace, you will not find serenity, you will not find blissfulness, you will not find contentment. You will not feel at home, at ease in the universe. You will remain just an accident, you will never become essential.

Dogen is a very unique genius. He is saying, “You may be aware of your buddhahood or not aware of your buddhahood — don’t be worried. When the right time and the right season come you will blossom into a buddha.” Just wait … wait intelligently, wait without desire; enjoy waiting, make waiting itself a blissful silence, and whatever is your birthright is bound to flower. Nobody can prevent a bird from flying, nobody can prevent a cuckoo from singing, nobody can prevent a rose from blossoming. Who is preventing you from becoming buddhas? Except you, nobody is responsible for it.
– Dogen, the Zen Master: A Search and a Fulfillment, Chapter #3

Dogen, a Zen master, used to say, when he felt hungry he would say, “It seems the universal feels hungry through me.” When he would feel thirsty he would say, “The existence is thirsty within me.” This is what this meditation will lead you to. Then everything disperses from your ego and becomes part of the universe. Then whatsoever happens, happens to existence itself; you are no more here. Then there is no sin, then there is no responsibility.
