Your mind is boring, utterly boring. Get out of the mind. At least for a few moments every day, put the mind aside, be utterly nude of the mind. And then you will know it is welling up within you — the freshness you are asking about. From where does it come? It comes from the deepest core of your being — and it does not really come. Suddenly you find it has always been the case. It has always been there like an undercurrent, underground, hidden behind many many layers of memories, dreams, desires.
