““Zen's object of worship cannot be named and determined as God, or Brahman, or Amitabha, or Creator, or Nature, or Reality, or Substance, or the like. Neither Chinese nor Japanese masters of Zen tried to give a definite name to their object of adoration. They now called Him That One, now This One, now Mind, now Buddha, now Tathagata, now Certain Thing, now the True, now Dharma-nature, now Buddha-nature, and so forth.””
