Date: June 25.
With Ven. Longyun, we went to San Diego to attend "Cognitive therapy and mindfulness."
We arrived at night. My mediation started from 9:30 to 11:30.
The experience: after formal meditation, I usually lie down and still try to mindful to the breath. That day, I did the same thing. Few minutes I lied down, suddenly, I feel my body like bubble evaporating. I don't think I had sensation feeling of the body, except the head. I was a little scared, but tried to remind calm and focusing that felling as I should do.
Ven. Longyun thought this was something would happen in the begining of meditation and something related to "Qi." If Qi unblocked, such thing will disappear eventually.
