Title:
Buddhism

Context:
In Theravada Buddhism there can be no divine salvation or forgiveness for one's karma, since it is a purely impersonal process that is a part of the makeup of the universe.[citation needed] In Mahayana Buddhism, the texts of certain Mahayana sutras (such as the Lotus Sutra, the Aṅgulimālīya Sūtra and the Mahāyāna Mahāparinirvāṇa Sūtra) claim that the recitation or merely the hearing of their texts can expunge great swathes of negative karma. Some forms of Buddhism (for example, Vajrayana) regard the recitation of mantras as a means for cutting off of previous negative karma. The Japanese Pure Land teacher Genshin taught that Amitābha has the power to destroy the karma that would otherwise bind one in saṃsāra.
