Pray Simply. Do not expect to find in your heart any remarkable gift of prayer.Consider yourself unworthy of it-then you will find peace. Use the empty, cold dryness of your prayer as food for your humility. Repeat constantly: “I am not worthy, Lord, I am not worthy!” But say it calmly, without agitation. This humble prayer will be acceptable to God.

+ Elder Macarius of Optina

You aren’t able to repent properly and to be alone in the heights of the love of God. That is to say, just God and you; just Christ and you. The love of Christ is offered and always passes through other people.
+ Elder Porphyrios the Kapsokalyvite (1906-1991)
