==By Discipline ==
I have known people with such opposite sides in their nature, so contradictory, that one day they could make a magnificent, luminous, powerful formation for realisation, and then the next day a defeatist, dark, black formation—a formation of despair—and so both would go out. And I was able to follow in the course of circumstances the beautiful one being realised, and while it was being realised, the dark one demolishing what the first one had done. And that is how it is in the larger lines of life as in its smaller details. And all that because one does not watch oneself thinking, because one believes one is the slave of these contradictory movements, because one says, "Oh! Today I am not feeling well. Oh! Today things seem sad to me", and one says this as if it were an ineluctable fate against which one could do nothing. But if one stands back or ascends a step, one can look at all these things, put them in their place, keep some, destroy or get rid of those one does not want and put all one's imaginative power—what is called imaginative—only in those one wants and which conform with one's highest aspiration. That is what I call controlling one's imagination.
