the monkey is born into his house as he awakens from the blackout. He does not know how he arrived in this prison, so he assumes he has always been there, forgetting that he himself solidified the space into walls.
Trungpa positions blackout as the primordial moment of ego-origination: the arising of a bounded self-sense from a prior state of unconscious openness, making ignorance of one’s own constructive activity the founding condition of conditioned existence.
