The Way of a Pilgrim is the anonymous memoir of a nineteenth-century Orthodox monk who wandered across Russia, continually reciting the simple, mantra-like Jesus Prayer:
Lord Jesus Christ, Son of God, have mercy on me, a sinner.
His observations are fascinating, and to a certain extent mirror the experiences of Hindu and Buddhist mystics in that the constant repetition of the mantra leads to heightened awareness of the eternal now. As the Pilgrim recounts:
When I prayed in my heart, everything around me seemed delightful
and marvelous. The trees, the grass, the birds, the air, the light
seemed to be telling me that they existed for man's sake, that they
witnessed to the love of God for man, that all things prayed to God and
sang his praise.
Clearly, the conclusions he draws about the relationship between God, man, and the natural world are Christian, but the experience itself seems to be remarkably universal.
