Nothing to learn only the Genjo Koan (another quote)
All ways of teaching, reading, and studying the Buddha Dharma lead to one point. Nothing else. Only one point. Picking and choosing doesn't matter. That only matters to you. What matters is the one point. What matters is not the clothes, books, or websites. Only the one point. What is all the stuff for? I think Suzuki Roshi explains it clearly.
The Blue Cliff Record, Case 61:
FUKETSU'S "ONE PARTICLE OF DUST"
How many people are suffering? "What is the matter? Let them suffer. Let them go in the wrong direction. That is not our problem. Let it go as they go. I will not do anything with you." That is, "We will not pick up any dust." But if you want to do something with them, or if you want to help them, at the same time many bad things will follow [laughs]. This is very interesting but very real.
As D?gen-zenji said, "Everything is buddha. So, there is enlightenment and defilement, birth and death, Buddha and sentient beings." If you pick up one thing there is birth and death, enlightenment and delusion, and Buddha and sentient beings. And something good and something bad. Even though your speech is good, many things will happen just because you picked up one thing. If you don’t do anything, nothing will happen. But because we do something many things will follow. That is actual fact. So we call it "Genj?-k?an." ["Actualizing the Fundamental Point," a fascicle of D?gen's Sh?b?genz?.] That is our k?an to solve—actual k?an we have.
If you don’t pick up anything, it means that if you understand what is the real teaching of Buddhism, it means what is the purpose of Buddhism. Purpose of Buddhism is not to establish Buddha's teaching, Buddha's groups, but to help people. And to help people going their own way. Just because they are not following their own way. So Buddha gives them some warning: "If you do not follow the right path, you will be lost." That is only reason why Buddha left his teaching for human being. So he doesn’t want to pick up anything. Or there is no need to pick up anything if all sentient beings follow right path. But most people or some Buddhist will make big mistake. They try to establish something for sake of Buddhism in its small, narrow sense. Then that is big mistake
