text: The Dharmaguptaka (Sanskrit: धर्मगुप्तक; ) are one of the eighteen or twenty early Buddhist schools, depending on the source. They are said to have originated from another sect, the Mahīśāsakas. The Dharmaguptakas had a prominent role in early Central Asian and Chinese Buddhism, and their Prātimokṣa (monastic rules for bhikṣus and bhikṣuṇīs) are still in effect in East Asian countries to this day, including China, Vietnam, Korea, and Japan as well as the Philippines. They are one of three surviving Vinaya lineages, along with that of the Theravāda and the Mūlasarvāstivāda.
  Etymology
  Guptaka means "preserver" and dharma "law, justice, morality", and, most likely, the set of laws of Northern Buddhism.
  Doctrinal development
  Overview
  The Dharmaguptakas regarded the path of a śrāvaka (śrāvakayāna) and the path of a bodhisattva (bodhisattvayāna) to be separate. A translation and commentary on the Samayabhedoparacanacakra reads:
  According to the Abhidharma Mahāvibhāṣā Śāstra, the Dharmaguptakas held that the Four Noble Truths are to be observed simultaneously.
  Vasubandhu states that the Dharmaguptakas held, in agreement with Theravada and against Sarvāstivāda, that realization of the four noble truths happens all at once (ekābhisamaya).
  The Dharmaguptaka are known to have rejected the authority of the Sarvāstivāda prātimokṣa rules on the grounds that the original teachings of the Buddha had been lost.
