[When] you get to the end of a meeting, a day, let that unravel. You cultivate the wisdom of no-performance and no-result. You listen to any judgements that are rattling in your mind, establish mindfulness on the mind-state and its feeling, then let the defenses and identities go. 

It’s a matter of acknowledging the inner helicopter that is hovering over ‘If only this’ and ‘I should have said that’ and ‘How dare they do this!’ and steadily touching the ground. Allow the feeling to be felt and breathe through it. Let it end, even let the wish that it all end come to an end. When the rotor blades stop, just here, on the other side of failure, is purity and release.
