-But rational thoughts lead only to rational thoughts, whereas irrational thoughts lead to new experiences.

In this world, there are two times. There is mechanical time and there is body time. The first is as rigid and metallic as a massive pendulum of iron that swings back and forth, back and forth, back and forth. The second squirms and wriggles like a bluefish in a bay. The first is unyielding, predetermined. The second makes up its mind as it goes along.

And at the place where time stands still, one sees lovers kissing in the shadows of buildings, in a frozen embrace that will never let go. The loved one will never take his arms from where they are now, will never give back the bracelet of memories, will never journey afar from his lover, will never place himself in danger of self-sacrifice, will never fail to show his love, will never become jealous, will never fall in love with someone else, will never lose the passion of this instant of time.

In a world without future, each moment is the end of the world.

Who would fare better in this world of fitful time? Those who have seen the future and live only one life? Or those who have not seen the future and wait to live life? Or those who deny the future and live two lives?

The tragedy of this world is that everyone is alone. For a life in the past cannot be shared with the present.

Events, once happened, lose reality, alter with a glance, a storm, a night. In time, the past never happened. But who could know? Who could know that the past is not as solid as this instant.

Some make light of decisions, arguing that all possible decisions will occur. In such a world, how could one be responsible for his actions? Others hold that each decision must be considered and committed to, that without commitment there is chaos. Such people are content to live in contradictory worlds, so long as they know the reason for each.

Is it possible for a person to love without wanting love back? Is anything so pure? Or is love, by its nature, a reciprocity, like oceans and clouds, an evaporating of seawater and a replenishing by rain?

Such is the cost of immortality. No person is whole. No person is free. Over time, some have determined that the only way to live is to die. In death, a man or a woman is free of the weight of the past [and the future].

A person who cannot imagine the future is a person who cannot contemplate the results of his actions. Some are thus paralyzed into inaction.

Suppose time is a circle, bending back on itself. The world repeats itself, precisely, endlessly.

In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.

Imagine a world in which there is no time. Only images.
