I wonder if there is a word for this state of mind. Kind of a relaxed, unhurried creative state. I think John Cleese referred to this as the 'open state' but it almost seems more of a subset. Perhaps the buddhist texts have a word for this, although I'm thinking of a more general state of mind, not necessarily just after meditation.

It's a dawning of mind, grateful state. It's like peeling one layer off the onion.
