Conversation and acquaintance with a saint will impart sanctity. - Ignatius Bryanchaninov

All the saints assiduously avoided distraction. Constantly, or at the very least as often as possible, they concentrated their thoughts within themselves, paying attention to every movement of the mind and heart, directing these according to the commands of the Gospels.

Consider how wise and careful you must be. Do not gamble with your eternal fate.

The only mind that is healthy is the one that wholly and completely follows the teaching of Christ.
