We do very well (Saint Seraphim of Sarov)

We have to try to be free of impure thoughts, especially when we pray to God. Because stench can’t co-exist with fragrance. If we don’t allow wicked thoughts, which come from the devil, we’re doing very well. Because the impure spirit is able to exercise effective influence only on people who suffer from the passions. Those who don’t, he tries to influence from afar.
