There is no reaching the Self. If Self were to be reached, it would mean that the Self is not here and now but that it is yet to be obtained. What is got afresh will also be lost. So it will be impermanent. What is not permanent is not worth striving for. So I say the Self is not reached. You are the Self; you are already That.

If the mind falls asleep, awaken it. Then if it starts wandering, make it quiet. If you reach the state where there is neither sleep nor movement of mind, stay still in that, the natural (real) state.
