Ashtavakra Gita 15.17 -

As discussed and proved earlier, this universe is a clear illusion. It exists and is experienced every day for only 17 hours or so and that too by those who remain wakeful. One’s wakefulness is the precondition to experience the world. Without the subject experiencer, no experiencing or experience can be had. The source and cause is the experiencing individual, and that too when he is awake by himself. To accept anything as real presence, it should exist for ever – in the past, present and future. This is not true of the world. So admit and realize that the universe is an illusory display.

Once it is so, why crave at all for anything in it, however alluring it may seem? Say good bye to desiring. You are the presence, which is ever conscious. At no time you are unconscious. Even in swooning, one wakes up to say he did not know anything.

Remain Consciousness alone, not involved in or with anything else, as no such thing is there. Automatically, you become restful, peaceful and calm. You do not have to cultivate peacefulness or quietitude. As even the most worried and anxious person leaves his tense wakefulness, lies coiled up in sleep, here too the seeker can get into this inner state of calm and poise all by himself. He should be inspired by the truth of his being Consciousness, having no connection with any other existence at all!
