The Kukkuṭika (Sanskrit; traditional Chinese: 雞胤部; ; pinyin: Jīyìn Bù) were an early Buddhist school which descended from the Mahāsāṃghika.
It is likely that the name Kukkuṭika or Kukkulika originated from the Kukkuṭrārāma monastery at Pāṭaliputra, which was an early center for the Mahāsāṃghikas.
There were numerous variations of this name, such as Kukkuṭika, Kukkulika, Kaukkuṭika, Kaurukullaka, and Gokulika.
The name Gokulika means "Cinder", and refers to the doctrine that all conditioned phenomena necessarily involve suffering, and that they are like an "inferno of ashes."
The Samayabhedoparacanacakra of Vasumitra regards the Ekavyāvahārika, Kukkuṭika, and Lokottaravāda as being doctrinally indistinguishable. According to Vasumitra, 48 theses were held in common by these three Mahāsāṃghika sects. Of these 48 special theses, 20 points concern the supramundane nature of buddhas and bodhisattvas. According to the Samayabhedoparacanacakra, these four groups held that the Buddha is able to know all dharmas in a single moment of the mind. Yao Zhihua writes:
In their view, the Buddha is equipped with the following supernatural qualities: transcendence (lokottara), lack of defilements, all of his utterances preaching his teaching, expounding all his teachings in a single utterance, all of his sayings being true, his physical body being limitless, his power (prabhāva) being limitless, the length of his life being limitless, never tiring of enlightening sentient beings and awakening pure faith in them, having no sleep or dreams, no pause in answering a question, and always in meditation (samādhi).
