Here’s a practice that directly evokes the truth that there is no separate and enduring self, meditated on in the context of interconnectedness.
Read these instructions and then sit up of lie down with your spine straight and your body relaxed, so that breath can flow easily in and out of your body. Close your eyes. Don’t do anything at all to manipulate or regulate your breathing. Let your experience be like wide-awake sleeping, with breath coming and going at its own rate.
Probably you’ll be aware of your diaphragm moving up and down as your chest expands and contracts. Of course you cannot feel that the exhaling air is rich in carbon dioxide and the inhaling air is rich in oxygen, but you probably know that. You also probably know that the green life in the world – the trees and vines and shrubs and grasses – are breathing in carbon dioxide and releasing oxygen back into the environment. The green world and your lungs, as long as they are both viable, are keeping each other alive.
Without any volition on your part, your body is part of the world happening, and the world is part of your body continuing. Nothing is separate. Your life is part of all life. Where is the self?’
