“In sleep a person passes in and out of two stages, dreaming and dreamless sleep. In the first, consciousness is withdrawn from the body and senses but still engaged in the mind. In dreamless sleep, however, consciousness is withdrawn from the mind as well. Then the thinking process – even the sense of “I” – is temporarily suspended, and consciousness is said to rest in the Self. In this state a person ceases to be a separate creature, a separate personality. In dreamless sleep, the Upanishads say, a king is not a king nor a pauper poor; no one is old or young, male or female, educated or ignorant. When consciousness returns to the mind, however, the thinking process starts up again, and personality returns to the body.”
― Krishna-Dwaipayana Vyasa, The Bhagavad Gita
