Mark the Ascetic - On the Spiritual Law 162-166

162. From a pleasure-loving heart arise unhealthy thoughts and words; and from the smoke of a fire we recognize the fuel.
163. Guard your mind, and you will not be harassed by temptations. But if you fail to guard it, accept patiently whatever trial comes.
164. Pray that temptation may not come to you; but when it comes, accept it as your due and not undeserved.
165. Reject all thoughts of greed, and you will be able to see the devil's tricks.
166. He who says he knows all the devil's tricks falls unknowingly into his trap.
