We first explore some further suggestions in the practice of metta, particularly related to working with distraction and an active mind, and then related to practicing when difficult states of mind, body, and emotion come up. We then begin to clarify the nature of compassion as the expression of the awakened heart in the presence of pain and difficulty. We link compassion to the understanding of the nature of how the conditioned mind reacts to what is painful, referring to the sequence from contact to grasping in the teaching on Dependent Origination, and the explication of the teaching of Dukkha (or "reactivity") and the end of Dukkha. We then explore further the receptive and active dimensions of compassion, some difficult distortions of compassion, and ways that compassion manifests toward self and others.
