Dawn & Dusk ........

Happiness and unhappiness are your moods and don't depend on the outside. This is one of the most basic things to be realised, because then much can be done. So the first thing to do is to realise that moods are not dependent on outside circumstances. The second thing to understand is that they depend on your unawareness. So just watch and become aware.
If happiness is there, just watch it and don't become identified with it. When unhappiness is there, again just watch.
It is just like morning and evening.
In the morning you watch and enjoy the rising sun. When the sun sets and darkness descends, that too you watch and enjoy. Don't use these words 'happiness' and 'unhappiness', because they carry judgements. Simply watch without judging -- this mood 'A', and this mood 'B', mm? do you follow? 'A' mood has gone, now 'B' mood is here, and you are simply a watcher. Suddenly you will realise that when you call happiness 'A', it is not so happy, and when you call unhappiness 'B', it is not so unhappy. Just by calling the moods A and B, a distance is created. When you say 'happiness', much is implied in the word. You are saying you want to cling to it, that you don't want it to go. When you say 'unhappy', you are not just using a word; much is implied in it. You are saying that you don't want it, that it should not be there. All these things are said unconsciously. So use these terms for the moods for seven days, and then tell me. Just be a watcher
if you are standing on top of the hill, and in the valley clouds and sunrises and sunsets come... sometimes it is day and sometimes night, mm? Just be a watcher on the hill far away
