In Hindu philosophy the whole creation is regarded as the Vishnu Lila, the play of Vishnu. Lila means dance or play. Also in Hindu philosophy, they call the world illusion; and in Latin the root of the word illusion is ludere, to play.
When your eyes are functioning well you don't see your eyes. If your eyes are imperfect you see spots in front of them. That means there are some lesions in the retina or wherever, and because your eyes aren't working properly, you feel them. In the same way, you don't hear your ears. If you have a ringing in your ears it means there's something wrong with your ears. Therefore, if you do feel yourself, there must be something wrong with you. Whatever you have, the sensation of I is like spots in front of your eyes - it means something's wrong with your functioning.
Philosophers, for example, often fail to recognize that their remarks about the universe apply also to themselves and their remarks. If the universe is meaningless, so is the statement that it is so.
Think about a piece of music - some great symphony - we don't expect it to get better as it develops, or that its whole purpose is to reach the final crescendo. The joy is found in listening to the music in each moment.
Zen is a liberation from time. For if we open our eyes and see clearly, it becomes obvious that there is no other time than this instant, and that the past and the future are abstractions without any concrete reality.
Since opposed principles, or ideologies, are irreconcilable, wars fought over principle will be wars of mutual annihilation. But wars fought for simple greed will be far less destructive, because the aggressor will be careful not to destroy what he is fighting to capture. Reasonable - that is, human - men will always be capable of compromise, but men who have dehumanized themselves by becoming the blind worshipers of an idea or an ideal are fanatics whose devotion to abstractions makes them the enemies of life.
The life of Zen begins, therefore, in a disillusion with the pursuit of goals which do not really exist the good without the bad, the gratification of a self which is no more than an idea, and the morrow which never comes.
Everybody should do in their lifetime, sometime, two things. One is to consider death...to observe skulls and skeletons and to wonder what it will be like to go to sleep and never wake up-never. That is a most gloomy thing for contemplation; it's like manure. Just as manure fertilizes the plants and so on, so the contemplation of death and the acceptance of death is very highly generative of creating life. You'll get wonderful things out of that.
