“Judgment of our neighbor drives away the activity of the Holy Spirit.  In difficult situations, like prison, evening (night) prayer is very helpful. Let us pray to the Good God with all our hearts! And as we do this, so that our prayer might be accepted, let us not bear grudges against anyone; and if anyone bears a grudge against us he won’t achieve anything—as long as we bear no hard feelings against anyone. Then our prayer will be acceptable to God. It is a great thing to pray without having any unpleasantness with anyone else! Nighttime prayer is very valuable.”
(Elder Proclu+ of Romania in pravoslavie.ru)
