In all memory, there is consciousness. Whenever wou recall things from the past, happy sad memories, consciousness is there. It's a conscious experience of words. You're sitting, walking, talking, eating, boating. So all that, there is awareness there. In dream in sleep, it continues. Without without consciousness, those things would not be possible.
Inspired by the 15th chapter of the Ashtavakra Gita, Swami Sarvapriyananda gives a discourse on the nature of the Self.
