It is related that a hermit consumed during one night ten mann of food and perused the whole Quran till morning. A pious fellow who had heard of this said: -It would have been more excellent if he had eaten half a loaf and slept till the morning.-
Keep thy interior empty of food
That thou mayest behold therein the light of marifet.
Thou art empty of wisdom for the reason
That thou art replete with food up to the nose.
