Let me share a little Ni tidbit here, a koan which has guided me many times before. Something just 'clicked' the first time I read it.
Here it is:
One day Unsho visited Tanzan, who was drinking wine at the time, not even a drop of which is suppposed to touch the tongue of a Buddhist.
"Hello, brother," Tanzan greeted him. "Won't you have a drink?"
"I never drink!" exclaimed Unsho solemnly.
"One who does not drink is not even human," said Tanzan.
"Do you mean to call me inhuman just because I do not indulge in intoxicating liquids!" exclaimed Unsho in anger. "Then if I am not human, what am I?"
Burping cat then burped.
