Hokaku introduces us to Koans, and relates how Case 7 of the Blue Cliff Record has knocked him off-kilter and destroyed his life, exactly as it is supposed to. He also talks about Buddha-nature, completely losing touch with himself and reality, identity (and lack thereof), faith and doubt, emotional instability, rivers, the cyclical nature of Zen practice, utter self-indulgence, fear, death, failure, falling apart and why he cries when peeling onions.
