僧羯磨 1.19

1.19

結同一說戒同一利養界法（時有二處別利養別說戒，諸比丘欲結共一說戒共一利養界。佛言：「自今已去，聽各自解界，然後白二結。」當敷座等，如前。應如是作。）

The procedure for demarcating a sīmā of common poṣadha and common material support. (At that time, there were two places with separate material support and separate poṣadha, and the bhikṣus wished to demarcate a common sīmā of common poṣadha and common material support. The Buddha said: "From this day forth, I allow them each to revoke their own sīmā first, and then demarcate [the new one] with a jñaptidvitīya-karman." The seats and so forth should be spread as before. It should be performed thus.)
