You cannot ask why. You can ask why only if you are doing something. If nature is doing something you cannot ask why; it is up to nature. And nature is not responsible; it is not going to answer you. It is completely silent. And for nature, millions of lives are nothing; for nature it may be just seconds. To you, millions of lives and years is a long history; for nature it is nothing. Nature is not worried, and nature is not interested in you particularly. Nature goes on working – someday it will happen, but you cannot ask why, because nature is silent.
If you are worried about why it has not happened yet, then you have to do something. If worry has entered you, then you have to do something. Only your doing will help you to come to a point where enlightenment can happen. Nature’s ways are very patient, slow. There is no hurry, because for nature there is no limit to time. It is eternal. There is no beginning and no end. But man has come to a point: he has become conscious, he has started asking.
A tree never asks – even the Bodhi tree under which Buddha became enlightened. The tree will never ask, “Why have I not become enlightened? – because I have also been existing for as many millions of years as you have existed, Gautam. Why?” The tree will never ask. The tree is absolutely natural. The questioning makes man unnatural. The unnatural has entered in you: you have started questioning why – why it has not happened yet.
This questioning is good, because it can lead you to a decisive moment where you can start working upon yourself. And man cannot leave it to nature, because man has become conscious. You cannot leave it to nature now. That’s why man has created religions. No animal has any religion. There is no need: they are not asking, they are not in a hurry. In nature everything is unhurried – moving so slowly as if not moving at all; continuously repeating the same pattern, infinitely repeating the same circle.
Man has become conscious. Man has become conscious of time, and the moment you become conscious of time, you are thrown out of eternity. Then you are in a hurry. So as man’s consciousness evolves more, he is more hurried, he becomes more and more time conscious. Go to a primitive society: they are not time conscious. The more civilized a society, the more time conscious. A primitive society is nearer nature: unhurried, it moves slowly. Just as nature moves, it moves. The more you become civilized, the more you become conscious of time. Really, time can be the criterion: how civilized a society is can be known by how time conscious it is. Then you are in a hurry, then you cannot wait, then you cannot leave it to nature. You have to take it in your own hands.
And man can take it in his own hands: he can do something and the process can be finished sooner. It can even be finished in a single moment. All that millions of years have not done, have not been able to do, you can do in a single moment. In that single moment you can become so intense that millions of years and millions of lives are traveled simultaneously.
