Oh?
Why?
Our priests, especially those who act as our spiritual fathers, teach us first and foremost, how to pray. It is through prayer that we “die to the self” and become increasingly focused on God and so we can experience the “uncreated energies” of God. No one, no priest, no hierarch, has any authority to order or direct us to do that. In fact, that any such person would attempt it is likely good evidence that he hasn’t even started to focus on God and “die to the self” and so should be avoided, at least disregarded as much as possible. Priests and especially hierarchs, have a hard time with that as the icon of the Ladder of Divine Ascent so graphically demonstrates.
