Quotations
Devotion to Amitābha Buddha is found within most schools of the Mahāyāna, but is the essence of Pure Land practice, which centres on the ‘Buddha invocation’ (Ch. nien-fo, Jap. nembutsu). This is the repetition of ‘Nan-mo A-mi-t’o Fo’ (Ch.) or ‘Nama Amida Butsu’ (Jap.), translations of the Sanskrit ‘Namo Amitābhāya Buddhāya’, meaning ‘Hail to Amitābha Buddha’.
1990, Peter Harvey, “Buddhist Practice: Devotion”, in An Introduction to Buddhism: Teachings, History and Practices, Cambridge: Cambridge University Press, page 187
"Pure Land Buddhism" refers to a set of beliefs and practices that espouses for its aspirants the realization of the stage of non-retrogression (avaivartika; pu t'ui-chuan) either in the present life or through rebirth in a Buddha land or realm (Buddha-kṣetra; fo-kuo) called "Sukhāvatī" (Land of Bliss). […] The Buddha Amitāyus (Wu-liang-shou; Immeasurable Life) or Buddha Amitābha (Wu-liang-kuang; Immeasurable Light) is the 'transcendant' Buddha who presides over the Sukhāvatī world-realm.

The Shorter Sukhavativyuha Sutra is chiefly concerned with describing the wonders of Amitabha Buddha's Pure Land, although it also discusses in some detail the characteristics of Amitabha himself.

Less well recognized, however, is the central role played in much of early medieval Pure Land Buddhism by deathbed practices and accompanying beliefs about the radical salvific power of one's last nenbutsu, whether understood as the contemplation of the Buddha Amitābha (or Amitāyus, Jpn. Amida) or the invocation of his name.

The overall programme of the Pure Land Hall represents the process of rebirth in Sukhāvatī, and the three standing Amitābhas in the shrine represent the three possible manifestations of Amitābha to the dying believer on earth, which is the beginning of that process.

In East Asia, the cult of Amitābha eventually became so widespread that it transcended sectarian distinction, and Amitābha became the most popular buddha in the region. In Tibet, Amitābha worship dates to the early propagation of Buddhism in that country in the eighth century, although it never became as prevalent as in East Asia.

Quotations
A letter from Mr. [Brian Houghton] Hodgson to Mr. Bayley, was then read, giving an outline of the theocracy of the Buddha system of Nepal. […] According to the information now communicated, the northern Buddhas acknowledge four sets of divine beings, or of superhuman objects of veneration. The first of these is, contrary to the generally supposed atheistical tendency of the faith, one primæval and uncreated deity. This first Buddha manifested five of his attributes, as five secondary Buddhas; in one of whom, Amitabha, or the 'immeasurably splendid,' in Prakrit and Pali, Amitabo, we recognise the Amito of the Japanese.
