“Amitabha Buddha” is Sanskrit. Amitabha means “infinite,” Buddha means “awakening.” This name therefore implies infinite enlightenment. “Infinite” describes that which is innate in the true nature: infinite wisdom, infinite virtues and abilities, and infinite auspicious marks. These three categories of “infiniteness” cover all the infinities in the whole universe. “Amitabha Buddha” is a name of the true nature. That is why Master Zhongfeng said “My mind is Amitabha Buddha; Amitabha Buddha is my mind.”
