I see many posts on how meditation really helps people. It seems to help with relaxation, pain reduction, sleep improvement, general sense of well being, etc. For those of you who DO meditate, I have three questions: 1) What benefits do you see from meditation? 2) How often do you do it? (and how long does it take?) 3) The big question: How did you start? Where did you learn to meditate? Classes, CD's, books? Any help would be appreciated!
