This Sunday, Michael played portions of a talk by John Peacock, on Papanca, the tendency of the mind to proliferate apparently random thoughts, and the practice of Metta meditation, and ways in which that might serve to tame the very basis of Papanca.
The complete talk is titled Papanca Part Three: The Brahma Viharas, was delivered on Muly 8 2011, and can be found at
