Picking up the thread of compassion training, as part of A Philosopher's Guide to Working with the Medicines of Our World, we contrast compassion with empathy distress. We also introduce the notion of the tonglen attitude, a special mindset that can empower and liberate our practice with any of the medicines of our World. Finally, we look at one way to understand one aspect of how compassion and tonglen function: a kind of magic mind synchrony in which self-regulation and co-regulation become integrated.
