Meditation on the Buddha Infinite Life Sutra ［観無量寿経］ (Chin Kuan-wu-liang-shou-ching; Kammuryōju-kyō): Abbreviated as the Meditation Sutra. A sutra said to have been translated into Chinese by Kālayashas between 424 and 442. The Buddha Infinite Life is also known as the Buddha Amida. This sutra is one of the three basic scriptures of the Pure Land school, which reveres that Buddha. According to the Chinese text, Shakyamuni Buddha expounded it in the royal palace at Rājagriha in Magadha, India, at the request of Vaidehī, who was grieving in prison over the evil acts of her son Ajātashatru, who had also imprisoned his father, King Bimbisāra, in order to become the new king. Shakyamuni employed supernatural powers to show her various pure lands, including Amida’s Pure Land of Perfect Bliss. Since Vaidehī preferred Amida’s Pure Land to all the others, Shakyamuni expounded sixteen types of meditation to attain rebirth there. This sutra inspired Shan-tao (613–681), a patriarch of the Pure Land school in China, when he was young, and he later wrote The Commentary on the Meditation on the Buddha Infinite Life Sutra. This commentary moved Hōnen to establish the Pure Land (Jōdo) school in Japan based on the sole practice of reciting the name of Amida Buddha. Only one Chinese translation of the sutra exists, and neither a Sanskrit text nor a Tibetan version is extant. Hence contemporary scholars view this sutra as having originated in either Central Asia or China.
