When I was beginning to learn Thai, I studied the language and meditation at a local temple here in Edmonton. The Thai monks taught me to speak, read and write as well as meditate. I did it on almost a daily basis for over 2 years. What I found was an extreme form of relaxation. I would do walking meditation for 30 minutes along with sitting for 30 with a group of others at the temple. I would almost always fall asleep, snoring loudly, during the sitting part. After wards my monk teacher would say to me "Gerry you fell asleep again.", then laugh. I do not think technically in proper meditation you should fall asleep thou some people do (including monks). I know I was very very relaxed and would doze off quite easily, usually within the first 10 minutes of the 30 minute sitting session. After I left the temple my stress level was very low, I felt completely refreshed and at peace. I highly recommend those interested give meditation a try!
