Evil thoughts are cast away only by good thoughts
Make out of your soul a welcoming house for our Lord!
The light of God, given to us in abundance through the Holy Mysteries and services, personal prayer, Jesus’ prayer and the study of patristic books, they all aim towards the same target: to make out of us a durable house. Saints pray for us in heaven and interfere for us, but we should also make an effort to build our spiritual house on healthy, durable and untainted and holy grounds.
The evil thought is casted only with a good one
The best way to gather your thoughts is having a main one that helps you to recognise the others, and to cast the evil and support the good ones. The easiest way is this prayer: ‘Lord Jesus Christ, Son of God, have mercy on me, a sinner!’ We say this in order to be able to be steadfast in good thoughts.
