天台菩薩戒疏 2.39

2.39

第三十一、不行救贖戒。菩薩發心慈救為本，況見尊危，輕心棄捨，內闕孝心，外乖慈愍，故制犯也。別具四緣：一、見三寶等在危，二、生知見想，三、無慈愍心，四、不救贖，便犯。就文為三：初、標名約時，列危難事。言「父母」者，諸佛菩薩能生法身，故彼形像即父母形像。「而菩薩」下，制作成持。三、「若不」下，違制結犯。並如文。

Thirty-first: the precept against failing to rescue and ransom. A bodhisattva's arousal of the aspiration takes compassionate rescue as fundamental; how much more so when seeing the venerable in danger—to cast them aside with a frivolous mind lacks filial devotion within and contradicts compassion without; therefore, an offense was instituted. It specifically comprises four conditions: 1. seeing the Three Jewels and so forth in danger; 2. generating the perception of knowing and seeing; 3. lacking a compassionate mind; and 4. failing to rescue and ransom—whereupon one commits an offense. The text has three parts: first, indicating the name in relation to the time and listing the dangerous situations. As for "parents," the Buddhas and bodhisattvas can give birth to the dharmakāya; hence their images are indeed the images of one's parents. From "yet a bodhisattva" onward, it institutes the practice of upholding. Third, from "if one does not" onward, it determines the offense for violating the prohibition. All are as in the text.
