In Sufi terms these two aspects of will are called Kaza and Kadr. Sometimes we think, "If I could see that friend it would be so pleasant", and at the same time there comes a desire, "If I could have some nice flowers", and then a friend comes bringing a bunch of our favorite ones. Or we may desire to have fish to eat, and the cook brings a savory dish of fish. Sometimes this is due to the strength of one's own will, and sometimes it is the soul working in harmony with the divine will. One only knows when it is in harmony with the divine will and when not by noting the results, and the one who knows beforehand is the seer.
