In past weeks I've been pulling inspiration from the Satipatthana Sutta, the foundational teachings on mindfulness. I've been linking them to some of it's underpinning truths of change, impermanence, suffering, and freedom from it. I'd like to continue on this thread for tomorrow's talk and bring in the third foundation, the foundation of the mind.. We'll explore how, when we aren't lost in it, the mind is a fascinating subject for our attention. When we understand our mind more fully, we can more fully understand who we are. We'll use this theme to understand better the truth of self and not-self.
