If the desires are not fulfilled the soul is naturally on fire. But there is no reason why the desire should not be fulfilled; the very existence of a desire promises its fulfillment. In the heart of man is the desire of God. The Qur'an says that without the will of God not even a single atom can move. This shows that every wave of thought and feeling, every motion and action is from God. Every thought that comes to our mind is God's thought, even if it appears to be a thought of everyday life in the world.
