Hmmm... I've never heard of meditaton involving sufffering....
Anyway, I was fortunate enough to have a happy childhood. So I probably don't have a whole lot of "stuff" that needs to come out. As I mentioned, I'm already a pretty happy (and extremely optimistic) person so my intention with these CDs were not to make me happy, but to reach higher states of consciousness and experiment further with lucid dreams and OBEs. The endorphin rush feeling was an unexpected side effect of the Hemi-Sync. I can live without it, and usually do, but it's a nice extra benefit.
For example, a runner can get an extra endorphin boost when he runs which is a nice bonus, but he could be perfectly happy also when not running.
There are, however, some positive long term effects for me from Hemi-Sync and the exploration of different states of consciousness. I tend to look at thinks from a higher perspective in the sense that I really do believe we are more than our physical bodies, and that alone can make life seem kind of magical.
