Prayer is the laying aside of thoughts.

If your spirit still looks around at the time of prayer, then it does not yet pray as a monk. You are no better than a man of affairs engaged in a kind of landscape gardening.

Do not be troubled if you do not immediately receive from God what you ask Him; for He desires to do something even greater for you, while you cling to Him in prayer.

A man who worships in Spirit and Truth no longer honors the Creator because of His works, but praises Him because of Himself.

The further the soul advances, the greater are the adversaries against which it must contend.

The Holy Spirit, out of compassion for our weakness, comes to us even when we are impure. And if He finds our intellect truly praying to Him, He enters it and puts to flight the whole array of thoughts and ideas circling within it, and He arouses it to a longing for spiritual prayer.

Remember how the Lord rebukes Martha when He says: 'You are anxious and troubled about many things: one thing alone is needful' (Lk. 10:41-42) ? to hear the divine word; after that, one should be content with anything that comes to hand.
