Here's an example: someone says, "Master, please hand me the knife," and he hands them the knife, blade first. "Please give me the other end," he says. And the master replies, "What would you do with the other end?" This is answering an everyday matter in terms of the metaphysical. When the question is, "Master, what is the fundamental principle of Buddhism?" Then he replies, "There is enough breeze in this fan to keep me cool." That is answering the metaphysical in terms of the everyday, and that is, more or less, the principle zen works on. The mundane and the sacred are one and the same.
Buddhism ... is not a culture but a critique of culture, an enduring nonviolent revolution or "loyal opposition" to the culture in which it is involved.
If scientific analysis were conclusively to demonstrate certain claims in Buddhism to be false, then we must accept the findings of science and abandon those claims.
To observe and watch one's own mind is something really interesting. The untrained mind will run and follow its old habit patterns. Because it has not been trained and taught, it will get lost in all kinds of stories and issues. Therefore we have to train our mind. The meditation practice in Buddhism is all about training one's own mind.
Buddha taught kindness towards lower beings; and since then there has not been a sect in India that has not taught charity to all beings, even to animals. This kindness, this mercy, this charity - greater than any doctrine - are what Buddhism left to us.
Buddha himself taught different teachings to different people under different circumstances. For some people, there are beliefs based on a Creator. For others, no Creator. The only "definitive truth" for Buddhism is the absolute negation of any one truth as the Definitive Truth.
