When in deep sleep we have absolutely no sense of Time's existence at all. We are then in eternity! When we become thoroughly convinced of the illusoriness of time, and make this conviction a settled attitude, eternity reveals itself even during the waking state. This is life in the Overself. This is not the same as totalizing the past present and future; all those belong to illusion. This realization gives perfect peace.
