On the idea of "already being one with the Universe"... do read the collected writings and talks of Jiddu Krishnamurti. The tome I have read is called Total Freedom. Also, D.E. Harding's "On Having No Head" actually has a few exercises you can do to help one see there is no separation between seer and seen.
Aikido, chado or even a walk in the woods (among a endless number of other activities)are methods one can use to be aware of the obvious.
Thinking deeply in a shallow way????
