俱舍論疏 15.103

15.103

論「不律儀者至為名處中者」，問也。若有惡戒，因受近住，捨此惡戒。明相生時近住既捨，得惡戒不？若得惡戒，名不律儀者；若不得惡戒，名處中者。

On the Śāstra's statement, "Does one of non-restraint... or is one called intermediate?": this is a question. If someone has bad morality and, because of receiving the upavāsa precepts, abandons this bad morality: when dawn breaks and the upavāsa is abandoned, does one re-acquire bad morality or not? If one acquires bad morality, one is called one of non-restraint; if one does not acquire bad morality, one is called intermediate (madhyastha).
