"You should devote your moments of solitude exclusively to working for God - to prayer and the thought of God. These practices, if followed even reasonably aright, will not allow you to grow bored. For they bring spiritual consolation such as nothing else on earth can give."
- St. Theophan the Recluse as found in The Art of Prayer: An Orthodox Anthology, Timothy Ware, ed., Faber and Faber, 1966, p. 252.
