Meditation on a passage involves silent, focused repetition during meditation of memorized selections from scriptures of the world and writings of great mystics. According to Easwaran, the practice of meditating on a specific passage of text (Easwaran suggests the Prayer of Saint Francis or Psalm 23 as examples) has the effect of eventually transforming "character, conduct, and consciousness." The term passage is chosen to describe a spiritually-inspired text that one meditates on, during an extended period of time set aside for meditation, as compared to a mantram (or mantra). Easwaran collected an anthology of selections from the world's spiritual texts, God Makes the Rivers to Flow, for use in meditation.
