Continuity of openness of the portal of the heart. Please Note: This series of talks is from a retreat led by Rob Burbea and Catherine McGee for experienced practitioners. The requirements for participation included some understanding of and working familiarity with practices of emptiness, samatha, metta, the emotional/energy body, and the imaginal, as well as basic mindfulness practice. Without this experience it is possible that the material and teachings from this retreat will be difficult to understand and confusing for some.
