[Zen] Hakuin's Zen

[ED]

"For Hakuin, what was most important was the breakthrough *kensho*
experience, reached after years of rigorous meditation practice; apart
from *kensho*, the words and ideas of Zen are worthless and meaningless.

Hakuin's Zen represents a level of authenticity consonant with the
height of Zen in the T'ang Dynasty.

It is a Zen that focuses on the central matter relentlessly, and has
absolutely no use for anything that serves to distract from this."
