Was Sariputta and his disciples the editors of the Abhidhamma texts?

"According to this tradition, just prior to his seventh annual rains retreat the Blessed One ascended to the Tavatimsa heaven and there, seated on the Pandukambala stone at the foot of the Paricchattaka tree, for the three months of the rains he taught the Abhidhamma to the devas who had assembled from the ten thousand world-systems. He made the chief recipient of the teaching his mother, Mahamaya-devi, who had been reborn as a deva. The reason the Buddha taught the Abhidhamma in the deva world rather than in the human realm, it is said, is because in order to give a complete picture of the Abhidhamma it has to be expounded from the beginning to the end to the same audience in a single session. Since the full exposition of the Abhidhamma requires three months, only devas and Brahmas could receive it in unbroken continuity, for they alone are capable of remaining in one posture for such a length of time.

However, each day, to sustain his body, the Buddha would descend to the human world to go on almsround in the northern region of Uttarakuru. After collecting almsfood he went to the shore of Anotatta Lake to partake of his meal. The Elder Sariputta, the General of the Dhamma, would meet the Buddha there and receive a synopsis of the teaching given that day in the deva world: "Then to him the Teacher gave the method, saying, 'Sariputta, so much doctrine has been shown.' Thus the giving of the method was to the chief disciple, who was endowed with analytical knowledge, as though the Buddha stood on the edge of the shore and pointed out the ocean with his open hand. To the Elder also the doctrine taught by the Blessed One in hundreds and thousands of methods became very clear."

Having learned the Dhamma taught him by the Blessed One, Sariputta in turn taught it to his own circle of 500 pupils, and thus the textual recension of the Abhidhamma Pitaka was established. To the Venerable Sariputta is ascribed the textual order of the Abhidhamma treatises as well as the numerical series in the Patthana. Perhaps we should see in these admissions of the Atthasalini an implicit acknowledgement that while the philosophical vision of the Abhidhamma and its basic architecture originate from the Buddha, the actual working out of the details, and perhaps even the prototypes of the texts themselves, are to be ascribed to the illustrious Chief Disciple and his entourage of students. In other early Buddhist schools, too, the Abhidhamma is closely connected with the Venerable Sariputta, who in some traditions is regarded as the literal author of Abhidhamma treatises." ~ Bhikkhu Bodhi
