Never have I dealt with anything more difficult than my own soul, which sometimes helps me and sometimes opposes me.
A man of bad character punishes his own soul.
Knowledge exists potentially in the human soul like the seed in the soil; by learning the potential becomes actual.
Remember 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.
The 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.
