Spiritual hunger is a living, radiant fire put by God into hearts so that the ego can be burned; when it has been burned, this fire becomes the fire of longing, which never dies, either in this world or the next. There is no quicker way to God than spiritual hunger; if it travels through solid rock, water gushes forth. Spiritual hunger is essential for the Sufis; it is the showering of God's mercy on them.
Many are avidly seeking but they alone find who remain in continual silence... Those who delight in a multitude of words, even though they say admirable things, are empty within. If you love truth, be a lover of silence. Silence like the sunlight will illuminate you in God and will deliver you from the phantoms of ignorance. Silence will unite you to God... More than all things, love silence; it brings you a fruit that tongue cannot describe. In the beginning we have to force ourselves to be silent. But then there is born something that draws us to silence... If you only practice this, untold light will dawn on you in consequence. After a while a certain sweetness is born in the heart of this exercise and the body is drawn almost by force to remain in silence.
