In the early Buddhist schools, the Mahāsāṃghika branch regarded the buddhas as being characterized primarily by their supramundane nature. The Mahāsāṃghikas advocated the transcendental and supramundane nature of the buddhas and bodhisattvas, and the fallibility of arhats. Of the 48 special theses attributed by the "Samayabhedoparacanacakra" to the Mahāsāṃghika Ekavyāvahārika, Lokottaravāda, and the Kukkuṭika, 20 points concern the supramundane nature of buddhas and bodhisattvas.
