Men have such a good opinion of themselves, of their mental superiority and intellectual depth; they believe themselves so skilled in discerning the true from the false, the path of safety from those of error, that they should be forbidden as much as possible the perusal of philosophic writings.
Al-GhazaliRemember it is the heart and not the body, which strives to draw near to God. By heart I do not mean the flesh perceived by the senses, but that secret thing which is sometimes expressed by spirit, and sometimes by soul.
Al-GhazaliThe soul should take care of the body, just as the pilgrim on his way to Makkah takes care of his camel; but if the pilgrim spends his whole time in feeding and adorning his camel, the caravan will leave him behind, and he will perish in the desert.
