Buddhists, particularly those affiliated with various forms of Mahayana, have long engaged in prayer and chanting as healing practices. Through chanting, buddhas and bodhisattvas are called upon to help prevent or cure illness, disasters, and bad luck. These incantations are often accompanied by incense burning, the giving of offerings, and other common forms of ritual devotion, and can be performed privately or in large communal rites. Texts often chanted for healing purposes by Mahayana practitioners include the Bhaiṣajyaguru Sūtra, the Great Compassion Mantra, and portions of the Lotus Sūtra. A wide range of other sūtras, dhāraṇīs, and/or mantras may be used in other forms of Buddhism.
