It will do me more to go back to Vipassana than any single thing I can do for myself. It puts you at the center and you just follow along, being true.
As far as long-term effects, I came out of the experience glowing. Heat didn't bother me. I saw clearly. The afterglow lasted for about three months. Slowly, I became a little bit agitated by things that didn't bother me during the period of afterglow. If I had continued to meditate regularly, I would have been fine. Centered. Since I didn't...Because I made excuses for myself...I'm in a not so great state these days. And yet, if I found myself again in the state after Vipassana, if I took care of myself and meditated, I would be in a much better mental state.
It does great things, but it's not a cure-all. It changed my life more than anything else has and is immensely powerful. It introduced me to myself. For that I will always be grateful. And I hope I respect myself enough to go back soon.
