The Mind Life Conference had a Harvard Scientist who worked with the mentally ill.  She asked if His Holiness would explain the best meditation to use.  His answer was “No.” Though startled, we realized that there are some things that one has to find out for himself.

“We come to understand that compassionate thought is the root of bodhichitta or awakening mind. This thought of enlightenment must be put into practice in conjunction with the wisdom that realizes the ultimate nature of all phenomena, emptiness. This wisdom should be a union of special insight and a calmly abiding mind single-pointedly focused on its object, emptiness.”
