Namo Amitabha Buddha” (meaning homage to the Amitabha Buddha, and the name “Amitabha” means boundless light and infinite life), “Amitabha Buddha,” or simply, but with equal reverence, “Amitabha.”
~ Quoted from On Chanting…
Recitation is one of the central practices of Pure Land Buddhism. It involves the concentrated and heartfelt repetitive recitation of “Namo Amitabha Buddha” (Homage to the Buddha of Boundless Compassion and Wisdom). In Chinese this phrase is “Namo Omito-Fo” or “Namo Amituofo”, in Japanese, “Namu Amida Butsu.”
