From the book What Really Matters: Searching for Wisdom in America, by Tony Schwartz, a quote from Sandra Maitri, a teacher of Hameed Ali’s Diamond Approach (she later wrote The Spiritual Dimension of the Enneagram):

“Emptiness can be experienced in very different ways,” Maitri explained, after we’d done the exercise. “Often you almost literally fear you’ll die if you stay in that emptiness, and in a sense that’s true. A given sector of the personality will die if you don’t keep trying to fill it up. But there is something deeper. Emptiness feels like a black hole when it’s viewed through the prism of the personality. But that same hole is experienced as open and pristine and very peaceful when you are in essence. It may take a leap of faith to let go into this emptiness — whether from courage or desperation. But when you do, it is very spacious, and it’s anything but deficient. It is the beginning of opening up to our true selves — to the empty space in which everything arises, to the ground of our fundamental nature.”

This popped up into my awareness after writing previously about jumping off the train, a form of ego death.
