"When light engages the heart, it causes an illumination of the path, a purification of the consciousness, an enlightenment of the intellect and an establishment of the foundations of dhikr and shukr and of beautiful worship."

Next Quote

The lights of some people precede their dhikr, while the dhikr of some people precede their lights. There is the one who does (loud) dhikr so that his heart be illumined; and there is the one whose heart has been illumined and he does (silent) dhikr.
