Dāthāvedhaka
Dāthāvedhaka:The Mahāvamsa Tīkā mentions (MT.176) two theras of this name,one a resident of the Kurundacullaka-parivena,and the other of the Kolambahālaka-parivena.They lived in the time of Bhāgineyya Dāthopatissa,and about fifty years after the secession of the Sāgalikā from the Dhammaruci-nikāya they set up a school of their own,in which they borrowed the Ubhato-vihanga from the Dhammarucikas and the Khandaka and Parivāra from the Sāgalikas.
