The whole approach of Mandukhi Upanishad is to enable you to see that the awareness is associated with waking, dreaming and deep sleep experiences. Sri Ramakrishna used this term: "What exactly happens at enlightened mind? Because you can't know it with the mind" It's consciousness without hands or eyes or mind. Aware of itself through awareness. That is enlightenment.
Swami Sarvapriyananda teaches one of the shortest and most profound upanishads accompanied by Gaudapada's Karika. This lecture covers Mantra 7 (Part 2).
