as the Śāriputra Abhidharma Śāstra of the Dharmaguptaka school and various texts from the Pudgalavada tradition. These different traditions have some similarities, suggesting either interaction between groups or some common ground antedating the separation of the schools. Traditional views In the Theravāda tradition it was held that the Abhidhamma was not a later addition, but rather was taught in the fourth week of Gautama Buddha's enlightenment. The Theravada tradition is unique in regarding its Abhidharma as having been taught in its complete form by the Buddha as a single teaching, with the exception of the Kathavatthu, which contains material relating to later disputes and was held to only have been presented as an outline. According to their tradition, devas built a beautiful jeweled residence for the Buddha to the north-east of the bodhi tree, where he meditated and delivered the Abhidharma teachings to gathered deities in the Trāyastriṃśa heaven, including his deceased mother Māyā. The tradition holds that the Buddha gave daily summaries of the teachings given in the heavenly realm to the bhikkhu Sariputta, who passed them on. The Sarvāstivāda-Vaibhāṣika held that the Buddha and his disciples taught the Abhidharma, but that it was scattered throughout the canon. Only after his death was the Abhidharma compiled systematically by his elder disciples and was recited by Ananda at the first Buddhist council. The Sautrāntika school ('those who rely on the sutras') rejected the status of the Abhidharma as being Buddhavacana (word of the Buddha), they held it was the work of different monks after his death, and that this was the reason different Abhidharma schools varied widely in their doctrines. However, this school still studied and debated on Abhidharma concepts and thus did not seek to question the method of the Abhidharma in its entirety. Indeed, there were numerous Abhidharma texts written from an Abhidharma perspective. According to K.L. Dhammajoti, the commentator Yaśomitra even states that "the Sautrantikas can be said to have an abhidharma collection, i.e., as texts that are declared to be varieties of sutra in which the characteristics of factors are described." Doctrine The Abhidharma texts' field of inquiry extends to the entire Buddhadharma, since their goal was to outline, systematize and analyze all of the teachings. Abhidharmic thought also extends beyond the sutras to cover new philosophical and psychological ground which is only implicit in sutras or not present at all. There are certain doctrines which
