The Holy Fathers say (this is how Fr. Cleopa began to express concisely his spiritual experience to us, inherited from the Holy Fathers and personally experienced by him, as every one of his words clearly confirms) that on the path of salvation one is tempted by the devil from eight sides: from the front, from behind, from the left, from the right, from above, from below, from inside, and from the outside.
4. There are two ways in which the devil tempts from the right. The first is when one performs good deeds and actions, but with a bad or malicious intent and purpose. For example, if one does good or acts well out of vainglory, to receive praise, to obtain a position, to acquire fame, or in order to attain some benefit for oneself – it follows that one is doing such good out of vanity, avarice, and greed. The performance of good deeds for bad purposes is sinful and vain. The Holy Fathers liken such a performance of good deeds (such as fasting and almsgiving) to a body without a soul, inasmuch as the purpose for which a deed is accomplished is its soul, while the deed itself is its body. Therefore, the performance of good deeds with an ungodly purpose is essentially a temptation coming from the right, that is, coming under the guise of good. The second demonic temptation from the right comes through various apparitions and visions, when one receives visions of the devil in the form of God or an Angel of God. The Holy Fathers call trusting these specters from the devil, or accepting these demonic phenomena, delusion or deception [prelest].
