Advice for the conquering of evil thoughts.
A certain brother once asked one of the elders, "How shall I overcome the evil thoughts which ceaselessly trouble me?" The elder said to him, "Do not attempt to strive with all of them. Strive only against one. All evil thoughts have a single head and source. In one man it is this, in another that. It is necessary, first of all, to find out each man for himself what is the origin of his evil thoughts. Then let him bend his energies to the conquest of that one thing, and all other evil thoughts will give way before him."
