The contemplative believer who remembers God will begin to enjoy the solitude and places of seclusion where voices and movements are hushed. There he will find strength of heart and will, and he will no longer be worried or depressed. Then he will begin to taste the sweetness of worship, of which he cannot have enough. In it, he will find abundance of pleasure and comfort - more than what he used to find in diversion and play, or in the satisfaction of worldly desires. When he experiences this state, many of the worldly concerns will disappear, as he is in a completely different world from the rest of humanity.

Ibn Al Qayyim, Madaarik As-Salikeen
