The new Sūtras were very different in style and tone, but were defended as ‘the word of the Buddha’ through various devices.(16) First, they were seen as inspired utterances coming from the Buddha, now seen as still contactable through meditative visions and vivid dreams. Secondly, they were seen as the products of the same kind of perfect wisdom which was the basis of the Buddha’s own teaching of Dharma (Pali Dhamma) (Asta.4). Thirdly, in later Mahāyāna, they were seen as teachings hidden by the Buddha in the world of serpent-deities (nāgas), until there were humans capable of seeing the deeper implications of his message, who would recover the teachings by means of meditative powers.
Each explanation saw the Sūtras as arising, directly or indirectly, from meditative experiences. Nevertheless, they take the form of dialogues between the ‘historical’ Buddha and his disciples and gods. The initial new Sūtras were regarded as the second ‘turning of the Dharma-wheel’ (see p. 24), a deeper level of teaching than the early Suttas, with the Buddha’s Bodhisattva disciples portrayed as wiser than his Arhat (Pali Arahat) disciples. Because of the liberating truth the Sūtras were seen to contain, there was said to be a huge amount of karmic fruitfulness in copying them out, and disseminating, reciting, expounding, understanding, practising and even ritually venerating them. Such claims suggest defensiveness on the part of a new, small movement trying to establish itself. Some of the Mahāyāna Sūtras may have been in part produced by the new breed of charismatic Dharma-preachers who championed them.
These monks, and some laypeople, directed their preaching both within and beyond the existing Buddhist community, to win converts. This they did by extolling the virtues of perfect Buddhahood, so as to elicit a conversion experience of profound psychological effect. This was the ‘arising of the thought of awakening (bodhi-citta)’, the heartfelt aspiration to strive for full Buddhahood, by means of the Bodhisattva path.
The new perspective on scriptural legitimacy led to the Mahāyāna having an open, ongoing ‘revelation’, which produced a huge outpouring of new Sūtras in India in the period up to around 650 ce. These were composed anonymously, often by a number of authors elaborating a basic text, to produce works frequently running to hundreds of pages in length.
In contrast, the early Suttas are ninety-five printed pages long at most, and often only run to a page or two. In certain early Suttas such as the Mahā- samaya (D.ii.253–62), the Buddha is a glorious spiritual being surrounded by countless gods and hundreds of disciples. The Mahāyāna Sūtras developed this style. In them, the Buddha uses hyperbolic language and paradox, and makes known many heavenly Buddhas and high-level heavenly Bodhisattvas, existing in many regions of the universe. A number of these saviour beings, Buddhas and in time Bodhisattvas, became objects of devotion and prayer, and greatly added to the appeal and missionary success of the Mahāyāna.
