The popular saying is “I think, therefore I am!” But I don’t think in sleep. Does it mean that I don’t exist in sleep? The truth is I am there in sleep, dream and waking. I am always there, whether I think or not.
Life, Love, Happiness, Peacefulness... these are pre-existent within. Mind rises over them, covers them, then foolishly seeks them outside and gets disappointed. By meditation and self-enquiry, disturbing thoughts are expelled, mind becomes clear, and Happiness is rediscovered.
