Achieving Buddha Consciousness
Master Goso Hoen Zenji said,
It is like when a water buffalo leaves the safety of its enclosure to the edge of a cliff over an abyss. His horns, head, and hoofs pass through, but why can't his tail?
Wu-Men then added the verse:
If the buffalo runs, he will fall into the abyss;
If he returns, he will be butchered.
That little tail
Is a very strange thing.
