There is a difference between the will and this feeling of tension, effort, of counting only on oneself, having recourse to oneself alone which personal effort means; this kind of tension, of something very acute and at times very painful; you count only on yourself and you have the feeling that if you do not make an effort every minute, all will be lost. That is a personal effort. But the will is something altogether different.
It is the capacity to concentrate on everything one does, do it as best one can and not stop doing it unless one receives a very precise intimation that it is finished. It is difficult to explain it to you. But suppose, for example, through a concurrence of circumstances, work comes into your hands. Take an artist who has in one way or another got an inspiration and resolved to paint a picture. He knows very well that if he has no inspiration and is not sustained by forces other than his own, he will do nothing much.
It will look more like a daub than a painting. He attempts, he tries to see, to feel what he wants his painting to express and in what way it should be expressed. He has his colours, he has his brushes, he has his model, he has made his sketch which he will enlarge and make into a picture, he calls his inspiration.
There are even some who manage to have a clear, precise vision of what is to be done. But then, day after day, hour after hour, they have this will to work, to study, to do with care all that must be done until they reproduce as perfectly as they can the first inspiration... That person has worked for the Divine, in communion with Him, but not in a passive way, not with a passive surrender; it is with an active surrender, a dynamic will.
The result generally is something very good. Well, the example of the painter is interesting, because a painter who is truly an artist is able to see what he is going to do, he is able to connect himself to the divine Power that is beyond all expression and inspires all expression. For the poet, the writer, it is the same thing and for all people who do something.
