In this Dharma talk, Joseph investigates the mindfulness of the dhamma, focusing in on the aggregates of perception and mental formations. Continuing a series of talks on the Satipatthana Sutra, Joseph explores the fourth foundation of mindfulness: the mindfulness of the dhamma. In this case, dhamma means categories of experience, the understanding of how different elements of the body and mind function. Beginning the session, Joseph explores the Five Aggregates of Clinging, particularly the aggregates of perception and mental formations, and their relation to our sense of self, and inevitable freedom.
