This is actually the seventh chapter of astava, which is called the boundless ocean. I am the unbounded deep in whom the waves of all the worlds naturally rise and fall. But i do not rise or fall. When you are comfortable, become aware again that you are sitting here on this chair.
Inspired by the 15th chapter of the Ashtavakra Gita, Swami Sarvapriyananda gives a discourse on the nature of the Self.
