The Ugraparipṛcchā Sūtra is an early Indian sutra which is particularly important for understanding the beginnings of Mahayana Buddhism. It contains positive references to both the path of the bodhisattva and the path of the arhat, the latter of which was denigrated as a lesser spiritual path in later Mahayana sutras. It also emphasises solitary spiritual practices instead of community-based ones much like the very early Rhinoceros Sutra.
History of the sutra
While no version in an Indo-Aryan language survives, extant versions of the Ugraparipṛcchā Sūtra include three Chinese translations, a Tibetan translation, and a Mongolian translation based on the Tibetan version. The Ugraparipṛcchā Sūtra was one of the first Buddhist texts to be brought to China and it was apparently very popular as it was translated into Chinese six times between the second and fifth centuries, appearing first as Heart Mirror sutra translated by An Xuan and Yan Fotiao during the Later Han and then by Dharmarakṣa during the Jin Dynasty. In the Chinese canon it is part of the Ratnakuta collection. It was also widely known in India, being one of the most quoted texts in both the Daśabhūmikā Vibhāṣā and Shantideva's Śikṣāsamuccaya. Jan Nattier has suggested that it is likely the text circulated in Dharmaguptaka circles early in its history.
Content of the sutra
The central themes of the Ugraparipṛcchā Sūtra are the practices of the householder and those of the bhikṣu and bhikṣuṇī, stressing the importance and superiority of the latter group. The sutra promotes the bodhisattva ideal as a difficult, strictly monastic path, taking thousands of lifetimes to complete and suited only for the few. It also does not mention any other central Mahayana doctrines or place its teachings in opposition to what would later be classified as "Śrāvakayāna" teachings. Because of this, scholars such as JanNattier believe it dates to an early period in the development of Mahayana Buddhism. The position of householder is seen as highly disadvantageous to religious practice in comparison to the life of a pravrajita and householders are urged to ordain as soon as they are able. In the Ugraparipṛcchā Sūtra, the practice of living as a forest bodhisattva is seen as preferable to being a village monk: Even when the bodhisattva enters the towns and cities to preach he must "keep a cave-and-forest mind, as when he dwells in his hermitage."
