Just what on earth is Japa meditation?
“Japa (Sanskrit: जप) is a spiritual discipline involving the meditative repetition of a mantra or name of God. The mantra or name may be spoken softly, enough for the practitioner to hear it, or it may be spoken purely within the recitor's mind. Japa may be performed whilst sitting in a meditation posture, while performing other activities, or as part of formal worship in group settings. The practice of repetitive prayer is present in varied forms within most religions in the world, although the Dharmic Religions generally give more emphasis to it as a specific discipline.”
