“If we do not feel consolation during prayer, then something is wrong. It means we have to repent and correct ourselves in something. Some wrongly say that this happens because of the envy and wiles of the devil. In fact it is the Lord is saying to us, “I don’t understand the way you are addressing Me”. Prayer, just like Holy Communion—is a Sacrament. One has to prepare for it and have a clean conscience.”
(Elder St. Paisios in ‘St. Paisios the Hagiorite’)
