"As St. Paul says: “The letter killeth (that is, all formal practices) but the spirit maketh alive (that is, inner experience of the Truth). Realize this clearly, that whatever leads you closest to this inner truth, you are to follow in all you do. Let your spirit be uplifted and not downcast, burning and yet pure, silent and still.
"You need not say to God what you need or desire, for he knows it all beforehand. Christ said to his disciples: “When you pray, use not vain repetitions as the heathen do: for they think that they shall be heard for their much speaking.” That we may follow this peace and inward silence, that the eternal Word may be spoken in us and understood, and that we may be one with him, may the Father help us, and the Word, and the Spirit of both. Amen."
