Waking and dreaming state is a knowing thing going on. Deep sleep seems to be no consciousness at all. The Mandukkyo-penisher is not even interested in the states of consciousness. It's not interested in waking, not even interest in the waker. Jung is interested. Goudapada is not interested. We are talking about dream state.
Swami Sarvapriyananda teaches one of the shortest and most profound upanishads accompanied by Gaudapada's Karika. This lecture covers Mantra 5-6.
