Fasting is not merely staying hungry and thirsty; rather its reality and its impact can only be gained through experience. It is human nature that the less one eats, the more one’s spirit is purified and thus his capacity for [spiritual] visions increases. The will of God is to decrease one kind of sustenance and to increase the other. A person who is fasting should always be mindful that he is not just required to stay hungry. On the contrary, he should remain engaged in the remembrance of God so that he can cut asunder ties of worldly desires and amusements and is wholly devoted to God. Hence, the significance of fasting is this alone that man gives up one kind of sustenance which only nourishes the body and attains the other kind of sustenance which is a source of comfort and gratification for the soul.”
