四分律刪繁補闕行事鈔 1.372

1.372

一受者得法以不。四律所明，必須十戒於前，後聽受具。文中不與受十戒，眾僧得罪。《多》云：所以制十戒者，為染習佛法故，不同外道一往頓受。佛法不爾，猶如大海，漸深漸入。

First: whether the recipient has obtained the Dharma or not. What is explained in the four Vinayas is that the ten precepts must precede, and only afterward is one permitted to receive the full [precepts]. In the text, if one does not confer the ten precepts, the assembled saṃgha incurs an offense. The Sarvāstivāda-vinaya-vibhāṣā states: 'The reason the ten precepts are instituted is to imbue and familiarize one with the Buddha's Dharma, not like the tīrthikas who receive them all at once. The Buddha's Dharma is not like that; it is like the great ocean, gradually deepening and gradually entering.'
