Mushin is a Zen expression meaning the mind without mind and is also referred to as the state of "no-mindness". That is, a mind not fixed or occupied by thought or emotion and thus open to everything. They also practice this mental state during everyday activities. It is somewhat analogous to flow experienced by artists deeply in a creative process. -From Wikipedia
Good music tends to help the flow, make sure to prep the playlist beforehand though, nothing worse than snapping out of creative zen when a shitty song comes on lol
I wish it was always there, but then thoughts come up and break it
