Sounds like fun. I have a few suttas in mind but we should probably start a new thread for that. If I have the time I’ll do it later today. Sometimes it’s not so much actually breaking the rule, just giving it another angle from which to interpret it. Please also post stuff that you find.
A while ago I have done a survey of the Sutta-EBTs collecting all instances where bhikkhunis, nuns, women, or any other kind of “female words” (mothers, sisters, wives, females, devis, goddesses, brahminis, female wanderers …) are mentioned. Quite interesting what came up. There are many independent and empowered women there. If you are interested, I could start a thread to share references for that, too.
By the way, concerning Sanghadisesa 3, it’s interesting to compare it with Chinese Bhiksuni Pratimoksas. Unlike the bhikkhu Patimokkha, the bhikkhunis’ is much less consistent across schools. And especially this rule apparently was confusing to people quite early on. In several Pratimoksas, this rule is broken up into several pieces, or covers situations different from the Pali. So the scope of this rule is not as clear-cut as one might think. After the vassa, I’m starting a project to translate the Chinese bhiksuni Pratimoksas into English for Suttacentral. Hopefully that will make them more accessible to people.
I like the Vinaya, too. I just wish that there wouldn’t be these situations where it clashes with common sense. Somehow the early Sangha seems to have gone more with wholesome intentions than with the letter of the rules.
