Yesterdays' session was great 
After meditation we had a Q&A session with our dharma teacher
on Sitting Meditation. So some of them queried on various problems
and issues, experiences on meditation. Some of them also shared
their own personal experiences (I suspect some of them are quite
experienced) and asked on various stages of Samadhis and luminous
state. The most comprehensive talk on meditation 'samadhi' stages
so far.
