The smaller Sukhâvatî-vyûha, represented as preached by Śâkyamuni at Śrâvasti, is occupied almost entirely with a description of the paradise. It marks a new departure in definitely preaching salvation by faith only, not by works, whereas the previous treatise, though dwelling on the efficacy of faith, also makes merit a requisite for life in heaven. But the shorter discourse says dogmatically "Beings are not born in that Buddha country as a reward and result of good works performed in this present life. No, all men or women who hear and bear in mind for one, two, three, four, five, six or seven nights the name of Amitâyus, when they come to die, Amitâyus will stand before them in the hour of death, they will depart this life with quiet minds and after death they will be born in Paradise."
The Amitâyur-dhyâna-sûtra also purports to be the teaching of Śâkyamuni and has an historical introduction connecting it with Queen Vaidehî and King Bimbisâra. In theology it is more advanced than the other treatises: it is familiar with the doctrine of Dharma-kâya (which will be discussed below) and it represents the rulers of paradise as a triad, Amitâyus being assisted by Avalokita and Mahasthâmaprâpta.85 Admission to the paradise can be obtained in various ways, but the method recommended is the practice of a series of meditations which are described in detail. The system is comprehensive, for salvation can be obtained by mere virtue with little or no prayer but also by a single invocation of Amitâyus, which suffices to free from deadly sins.
Strange as such doctrines appear when set beside the Pali texts, it is clear that in their origin and even in the form which they assume in the larger Sukhâvatî-vyûha they are simply an exaggeration of ordinary Mahayanist teaching.86 Amitâbha is merely a monk who devotes himself to the religious life, namely seeking bodhi for the good of others. He differs from every day devotees only in the degree of sanctity and success obtained by his exertions. The operations which he performs are nothing but examples on a stupendous scale of pariṇâmanâ or the assignment of one's own merits to others. His paradise, though in popular esteem equivalent to the Persian or Christian heaven, is not really so: strictly speaking it is not an ultimate ideal but a blessed region in which Nirvana may be obtained without toil or care.
Though this teaching had brilliant success in China and Japan, where it still flourishes, the worship of Amitâbha was never predominant in India. In Nepal and Tibet he is one among many deities: the Chinese pilgrims hardly mention him: his figure is not particularly frequent in Indian iconography87 and, except in the works composed specially in his honour, he appears as an incidental rather than as a necessary figure. The whole doctrine is hardly strenuous enough for Indians. To pray to the Buddha at the end of a sinful life, enter his paradise and obtain ultimate Nirvana in comfort is not only open to the same charge of egoism as the Hinayana scheme of salvation but is much easier and may lead to the abandonment of religious effort. And the Hindu, who above all things likes to busy himself with his own salvation, does not take kindly to these expedients. Numerous deities promise a long spell of heaven as a reward for the mere utterance of their names,88 yet the believer continues to labour earnestly in ceremonies or meditation. It would be interesting to know whether this doctrine of salvation by the utterance of a single name or prayer originated among Buddhists or Brahmans. In any case it is closely related to old ideas about the magic power of Vedic verses.
The five Jinas and other supernatural personages are often regarded as manifestations of a single Buddha-force and at last this force is personified as Âdi-Buddha.89 This admittedly theistic form of Buddhism is late and is recorded from Nepal, Tibet (in the Kâlacakra system) and Java, a distribution which implies that it was exported from Bengal.90 But another form in which the Buddha-force is impersonal and analogous to the Parabrahma of the Vedânta is much older. Yet when this philosophic idea is expressed in popular language it comes very near to Theism. As Kern has pointed out, Buddha is not called Deva or Îśvara in the Lotus simply because he is above such beings. He declares that he has existed and will exist for incalculable ages and has preached and will preach in innumerable millions of worlds. His birth here and his nirvana are illusory, kindly devices which may help weak disciples but do not mark the real beginning and end of his activity. This implies a view of Buddha's personality which is more precisely defined in the doctrine known as Ṭrikâya or the three bodies91 and expounded in the Mahâyâna-sûtrâlankâra, the Awakening of Faith, the Suvarṇa-prabhâsa sûtra92 and many other works. It may be stated dogmatically as follows, but it assumes somewhat divergent forms according as it is treated theologically or metaphysically.
A Buddha has three bodies or forms of existence. The first is the Dharma-kâya, which is the essence of all Buddhas. It is true knowledge or Bodhi. It may also be described as Nirvana and also as the one permanent reality underlying all phenomena and all individuals. The second is the Sambhoga-kâya, or body of enjoyment, that is to say the radiant and superhuman form in which Buddhas appear in their paradises or when otherwise manifesting themselves in celestial splendour. The third is the Nirmâna-kâya, or the body of transformation, that is to say the human form worn by Śâkyamuni or any other Buddha and regarded as a transformation of his true nature and almost a distortion, because it is so partial and inadequate an expression of it. Later theology regards Amitâbha, Amitâyus and Śâkyamuni as a series corresponding to the three bodies. Amitâbha does not really express the whole Dharma-kâya, which is incapable of personification, but when he is accurately distinguished from Amitâyus (and frequently they are regarded as synonyms) he is made the more remote and ethereal of the two. Amitâyus with his rich ornaments and his flask containing the water of eternal life is the ideal of a splendidly beneficent saviour and represents the Sambhoga-kâya.93 Śâkyamuni is the same beneficent being shrunk into human form. But this is only one aspect, and not the most important, of the doctrine of the three bodies. We can easily understand the Sambhoga-kâya and Nirmâna-kâya: they correspond to a deity such as Vishnu and his incarnation Krishna, and they are puzzling in Buddhism simply because we think naturally of the older view (not entirely discarded by the Mahayana) which makes the human Buddha the crown and apex of a series of lives that find in him their fulfilment. But it is less easy to understand the Dharma-kâya.
The word should perhaps be translated as body of the law and the thought originally underlying it may have been that the essential nature of a Buddha, that which makes him a Buddha, is the law which he preaches. As we might say, the teacher lives in his teaching: while it survives, he is active and not dead.
The change from metaphor to theology is illustrated by Hsüan Chuang when he states94 (no doubt quoting from his edition of the Pitakas) that Gotama when dying said to those around him "Say not that the Tathâgata is undergoing final extinction: his spiritual presence abides for ever unchangeable." This apparently corresponds to the passage in the Pali Canon,95 which runs "It may be that in some of you the thought may arise, the word of the Master is ended: we have no more a teacher. But it is not thus that you should regard it. The truths and the rules which I have set forth, let them, after I am gone, be the Teacher to you." But in Buddhist writings, including the oldest Pali texts, Dharma or Dhamma has another important meaning. It signifies phenomenon or mental state (the two being identical for an idealistic philosophy) and comprises both the external and the internal world. Now the Dharma-kâya is emphatically not a phenomenon but it may be regarded as the substratum or totality of phenomena or as that which gives phenomena whatever reality they possess and the double use of the word dharma rendered such divagations of meaning easier.96 Hindus have a tendency to identify
