Misery arises because we don´t allow change to happen. We cling, we want things to be static. If you love a woman you want her tomorrow too, the same way as she is yours today. That´s how misery arises. Nobody can be certain about the next moment – what to say about tomorrow?
A man of awareness knows that life is constantly changing. Life is change. There is only one thing permanent, and that is change. Except change, everything else changes. To accept this nature of life, to accept this changing existence with all its seasons and moods, this constant flow that never stops for a single moment, is to be blissful. Then nobody can disturb your bliss. It is your hankering for permanency that creates troubles for you. If you want to live in a life with no change – you are asking the impossible.
A man of awareness becomes courageous enough to accept the changing phenomena. In that very acceptance is bliss. Then all is good. Then you are never frustrated.
