All of the Buddha’s teaching is concerned with suffering and how to relieve suffering. In Zen we say that every human being’s job is the same-find your true self and help the world. When the Buddha left home he didn’t go to a library to try and find the answer to his great question. Instead, he started looking inside himself to find the answer. We are the same. Just like the Buddha, no outside source, even Zen teaching, can’t give us the answer. We must look inside-that’s the meaning of practice and meditation-looking inside to find the answer to the great question of life and death by returning to our original substance, your true self.
