"The Practice of the Presence of God," compiled by Father Joseph de Beaufort, is a collection of the wisdom and teachings of Brother Lawrence, a 17th century Carmelite monk. This collection of letters and other records records his conversations, thoughts, and philosophy, chiefly a development of an awareness of the presence of God.
Learn to feel yourself in other bodies, to know that we are all one. Throw all other nonsense to the winds. Spit out your actions, good or bad, and never think of them again. What is done is done. Throw off superstition. Have no weakness even in the face of death. Do not repent, do not brood over past deeds. Be aazaad (free).
-Swami Vivekananda
