A divine madness found in most religions to varying degrees. A manifestation of god-intoxication that releases one from the shackles of societal convention. As I see it, acute cosmic awareness reveals the insanity of our world and therefore makes the enlightened individual seem crazy by comparison.
This gentleman with a gun to his head is none other than the late Chögyam Trungpa Rinpoche, a trailblazing Tibetan monk who traded his saffron robes for ugly ties and polyester office attire upon discovering the spiritual playground of USA. He was the original mad man.
Trungpa's crazy wisdom takes on a specific character: "He subdues whoever needs to be subdued and destroys whoever needs to be destroyed," he says. "The idea here is that whatever your neurosis demands, when you relate with a crazy-wisdom person you get hit back with that. Crazy wisdom presents you with a mirror reflection... Crazy wisdom knows no limitation and no logic regarding the form it takes." The key nuance he makes is that the practitioner must practice "crazy gone wise" rather than "wisdom gone crazy."
