Buddhānusmṛti in the context of "Contemplation"

Amitābha (Sanskrit pronunciation: [ɐmɪˈtaːbʱɐ], "Measureless" or "Limitless" Light), also known as Amituofo in Chinese, Amida Butsu in Japanese, Amita-bul in Korean, A Di Đà Phật in Vietnamese, and Öpakmé in Tibetan, is one of the main Buddhas of Mahayana Buddhism and the most widely venerated Buddhist figure in East Asian Buddhism. Amitābha is also known by the name Amitāyus ("Measureless Life").

Amitābha is the main figure in two influential Indian Buddhist Mahayana Scriptures: the Sutra of Measureless Life and the Amitābha Sūtra. According to the Sutra of Measureless Life, Amitābha established a pure land of perfect peace and happiness, called Sukhāvatī ("Blissful"), where beings who mindfully remember him with faith may be reborn and then quickly attain enlightenment. The pure land is the result of a set of vows Amitābha made long ago. As his name means Limitless Light, Amitābha's light is said to radiate throughout the cosmos and shine on all beings. Because of this, Amitābha is often depicted radiating light, a symbol for his wisdom. As per the name Amitāyus, this Buddha is also associated with infinite life, since his lifespan is said to be immeasurable. Amitābha's measureless life is seen as being related to his infinite compassion.

The Nianfo (Chinese: 念佛; pinyin: niànfó, alternatively in Japanese 念仏 (ねんぶつ, nenbutsu); Korean: 염불; RR: yeombul; or Vietnamese: niệm Phật) is a Buddhist practice central to East Asian Buddhism. The Chinese term nianfo is a translation of Sanskrit buddhānusmṛti ("recollection of the Buddha"), a classic Buddhist mindfulness (smṛti) practice.

Nianfo focused on the Buddha Amitābha is also the most important practice in Pure Land Buddhism. In the context of East Asian Pure Land practice, nianfo typically refers to the oral repetition of the name of Amitābha through the phrase "Homage to Amitabha Buddha" (Ch: 南無阿彌陀佛, Mandarin: Nāmó Āmítuófó, Jp: Namu Amida Butsu, Vn: Nam-mô A-di-đà Phật; from the Sanskrit: Namo'mitābhāya Buddhāya). It can also refer to that phrase itself, in which case it may also be called the nianfo, or "The Name" (Japanese: myōgō 名号).
