You say that in heaven there is eternal beauty. The eternal beauty is here and now, not in heaven.

[M]ental peace is not meditation. Meditation is the flight beyond the mind. It has nothing to do with mental peace.

Live without expectations and there will be no frustration.

If whatsoever you have been living can be conveyed by words, that means you have not lived at all.

You cannot lose your real treasure.

You cannot stop smoking directly because it has many related things, implications. You are tense, and if you stop smoking you will start something else and the other may be more harmful. Don't go on escaping problems, face them. The problem is that you are tense, so the goal should be how to be non-tense, not, smoking or not smoking. Meditate. Relax your tensions without any object into the sky, allow catharsis to happen. When you are non-tense these things will become absurd, foolish, and they will drop. Food will change, your styles of living will change.

Zen lives in the present. The Whole teaching is: how to be in the present; how to get out of the past which is no more and how not to get involved in the future which is not yet, and just to be rooted, centered, in that which is.
