Change
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. Everything else except change, changes. To accept this nature of life, to accept this changing existence with all its seasons and moods, this constant flow which 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. You want to live in a life with no change, and that is not possible -- you are asking the impossible.
The child will become young, the young man will become old, the one who was alive yesterday will be dead today. If you accept all this change, this suchness of things, and you allow it to happen joyously -- knowing that's how life is -- then nobody can distract you from your bliss. Nobody can disturb your bliss. Then you move each moment with the flow of life.
Otherwise, people are always lagging behind. Life is always running ahead and they are far, far behind. They are simply dragging themselves. And they are so far behind that they are bound to be miserable -- because they will be almost dead, and by the time they reach to where life is right now, life has moved again. It is like a river: it is not stagnant, it is dynamic.
