the experience you have described that occurs after about 2 weeks is a very distinct state of mind. I find that I can to a certain extent reliability reproduce it (1) whenever I have a deadline and I'm procrastinating, (2) occasionally after smoking some marijuana (3) and on long distance runs.
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.
