The name Kāśyapīya is believed to be derived from Kāśyapa, one of the original missionaries sent by King Ashoka to the Himavant country. The Kāśyapīyas were also called the Haimavatas.
History
The Kāśyapīyas are believed to have become an independent schoolca. 190 BCE. According to the TheravadinMahāvaṃsa, the Kāśyapīya were an offshoot of the Sarvāstivāda. However, according to the Mahāsāṃghika account, the Kāśyapīya sect descended from the Vibhajyavādins. Xuanzang and Yijing note small fragments of the Kāśyapīya sect still in existence around the 7th century, suggesting that much of the sect may have adopted the Mahāyāna teachings by this time. In the 7th century CE, Yijing grouped the Mahīśāsaka, Dharmaguptaka, and Kāśyapīya together as sub-sects of the Sarvāstivāda, and stated that these three groups were not prevalent in the "five parts of India," but were located in the some parts of Oḍḍiyāna, Khotan, and Kucha.
Appearance
Between 148 and 170 CE, the Parthian monkAn Shigao came to China and translated a work which describes the color of monastic robes utitized in five major Indian Buddhist sects, called Da Biqiu Sanqian Weiyi. Another text translated at a later date, the Śāriputraparipṛcchā, contains a very similar passage corroborating this information. In both sources, members of the Kāśyapīya sect are described as wearing magnolia robes. The relevant portion of the Mahāsāṃghika Śāriputraparipṛcchā reads, "The Kāśyapīya school are diligent and energetic in guardingsentient beings. They wear magnolia robes."
Doctrines
In Vasumitra's history Samayabhedoparacanacakra, the Haimavatas are described as an eclectic school upholding doctrines of both the Sthaviras and the Mahāsāṃghikas. According to the Kathāvatthucommentary, the Kāśyapīyas believed that past events exist in the present in some form. According to A.K. Warder, the Kāśyapīya school held the doctrine that arhats were fallible and imperfect, similar to the view of the Sarvāstivādins and the various Mahāsāṃghika sects. They held that arhats have not fully eliminated desires, that their "perfection" is incomplete, and that it is possible for them to relapse.
Texts
Some tentatively attribute the GāndhārīDharmapada to the Kāśyapīya school. An incomplete translation of the Saṃyukta Āgama that is in the Chinese Buddhist canon is believed to be that of the Kāśyapīya sect. This text is different from the complete version of the Saṃyukta Āgama, which came from the Sarvāstivāda sect.
