The Fathers on Prayer
When mind and heart are united in prayer and the soul is wholly concentrated in a single desire for God, then the heart grows warm and the light of Christ begins to shine and fills the inward man with peace and joy.
We should thank the Lord for everything and give ourselves up to His
will; we should also offer Him all our thoughts and words, and strive
to make everything serve only His good pleasure.
St. Seraphim of Sarov
Prayer is a great weapon, a rich treasure, a wealth that is never exhausted, an undisturbed refuge, a cause of tranquillity, the root of a multitude of blessings and their source.
St. John Chrysostom
Prayer is a conversation directly with God, being always with God,
having one's soul united with Him and one's mind inseparable. A person
becomes one with the angels and unites with them in perpetual praise
and longing for God.
St. Symeon of Thessaloniki
