To find a buddha, you have to see your nature. Whoever sees his or her nature is a buddha. If you don't see your nature, invoking buddhas, reciting sutras, making offerings and keeping precepts are all useless. Invoking buddhas results in good karma. Reciting sutras results in good memory. Keeping precepts results in a good rebirth. And making offerings results in future blessings. But no buddha.

Nan-in, a Japanese master during the Meiji era (1868-1912), received a university professor who came to inquire about Zen.
Nan-in served tea. He poured his visitor's cup full, and then kept on pouring.
The professor watched the overflow until he no longer could restrain himself. "It is overfull. No more will go in!"
"Like this cup," Nan-in said, "you are full of your own opinions and speculations. How can I show you Zen unless you first empty your cup?"

If you seek to aid everyone that suffers in the galaxy, you will only weaken yourself ... and weaken them. It is the internal struggles, when fought and won on their own, that yield the strongest rewards… If you care for others, then dispense with pity and sacrifice and recognize the value in letting them fight their own battles.

Darkness is a friend, an ally. Darkness allows us to understand others, to see what they value when they believe no one else is looking. It allows us to be honest with ourselves, to express those values that we would disavow in the light. The light blinds us. It is only in the dark that we see clearly, and there is a great dark hidden among these worlds.
