Mindfulness has set the stage for post-mindfulness practices, including the meta-meditations of Dark Retreat, Reverse Meditation, and the Nocturnal Meditations. What are these practices, how can they benefit the world, and how do I engage in them? Each of these meditations transcend but include mindfulness, taking us to the farthest reaches of spiritual evolution and the very edge of mind. They serve to integrate day and night, life and death, pleasure and pain, and are uniquely situated to deliver the integralist to their fullest potential. We’ll explore the origins of these meditations, the science that is underway to support them, and their immediate applicability in helping us deal with the meta-crises.
