How can one change one's will into the Divine Will?…
Well, first you must want it. Afterwards. you must have a great aspiration. And then you must continue to want it, and continue to aspire and not give way when difficulties come, and continue until you succeed. That is all. And then, a certain number of things are necessary, as for example not to be selfish, not to have a small narrow- mindedness, not to live with preferences, not to have desires, not to have mental opinions – many things. It is a fairly long process because you must change your ordinary nature. This is the first condition.
To break all the limits of one's mind, break all the desires of one's vital, break all the preferences of one's physical nature. After that one may hope to be in contact with the Divine Will; and then, later, one must not only be in contact with it, but live integrally this Will, that is, be unified in all one's being: not have a single bit which goes on this side and another bit which goes on that. You must be entirely in one single will.
