What is the meaning of, “Whoever knows their Lord will not be concerned with other than Him?”

The meaning of the saying, “Whoever knows their Lord will not be concerned with other than Him,” is that whoever knows the Majesty, Might, and Perfection of God Most High will not find anything better than Him with which to concern themselves. No matter how distracted from Him they become, in spite of their desire they will be feel constricted and alone until they return to being concerned with the intimacy of their Lord, for that is true intimacy. This is accomplished through much remembrance of Him. He who tastes, knows, and he who knows, takes great draughts. So the one who has tasted the sweetness of intimacy with God will not find pleasure with another, and whoever remembers Him constantly will attain intimacy with Him, so that even if they are outwardly concerned with other than Him, their hearts are always with God.
