Is the gradual training found in the texts of the other early schools? I remember Sujato saying the gradual training is the early Buddhist scheme of practice, but I can’t seem to find it in the agamas.
Just doing a quick search, the suttas that mention anupubbasikkhā (gradual training) look to each have a Chinese parallel.
Here’s an example as well: The Long Discourses | 20. Ambāṣṭha
Note that some of the translations use ellipses for the gradual training. It looks like DN 2’s parallel DA 27 has that for example.
The Sarvastivada version is found in MA 80 Rough Cloth Sutra.
Thanks everyone. Much appreciated.
Oops. I probably would not have ever found that myself. Thanks!
One version is also found in the Yogācārabhūmi-Śāstra, within the Śrāvakabhūmi’s section on the “13 requisites” (sambhāra).
