菩薩從兜術天降神母胎說廣普經 1.74

1.74

「若有眾生分別諸行，此則可行、此不可行。若人貪著愛樂身者，即便為說四意止法，一一分別諸法要藏，暢達演說無量法界，即於胎中成無上道。

"If there are sentient beings who distinguish all practices—that this may be practiced, and this may not be practiced—if a person is greedy for and delights in the body, [the bodhisattva] immediately expounds to them the dharma of the four smṛtyupasthānas, distinguishing one by one the essential treasuries of all dharmas, fluently expounding the immeasurable dharmadhātu; they immediately accomplish the unsurpassed Path within the womb.
