It is the custom of the Orlando Insight Meditation Group to dedicate a meeting after a significant retreat experience to the sharing of the insights gained by the yogis during the retreat.  There were 21 people on the retreat, and several showed up to talk about it.  The changes in the mind that occur during a retreat are deep and function outside of the aware verbalizing functions of the brain.  Peter encourages yogis to talk in order to bring these deep changes more clearly into awareness, so they are more integrated and more accessible for future access.  Also, those who were not at the retreat can benefit from hearing about the insights and benefits gained from the intense practice of meditation on retreat.
