"Namo Amitabha" as he was called in full by Shakyamuni Buddha.

By accomplishment of his Name, Amitabha—or "Namo Amitabha" as he was called in full by Shakyamuni Buddha—ensured that the direct rewards (all beings or inhabitants in the Land of Bliss, including Amitabha himself) and the circumstantial rewards (all the landscapes and features of the Land of Bliss) were all manifestations of his Name. In Pure Land Buddhism, this is also known as "direct and circumstantial in a single entity." The Name "Namo Amitabha" is the body of Amitabha Buddha, filled with boundless kindness and compassion, perfect and complete wisdom, and splendid merits and virtues. It is also filled with Amitabha’s light, his vow-mind, his supernormal powers and energy, and all the exquisite perfections of Buddhahood.
