Meditation is not merely a formal sitting practice that we encounter each morning or in retreats. Instead it is a wakefulness that formal sitting practice is the entrance into, but that which we may find through waking, dreaming and deep sleep. Considered the practice most similar to our experience at death, dream yoga is about navigating in the real and unreal aspects of our experience without falling asleep to awareness. It is a practice of recognizing the nature of our minds. From the Six Yogas of Niguma.
