諸經要集 7.46

7.46

又雜阿含經云。爾時世尊告諸比丘。有三種子。何等為三。有隨生子。有勝生子。有下生子。何等為隨生子。謂子父母。不殺不盜。不婬不妄語。不飲酒。子亦隨學不殺等。是名隨生子。何等為勝生子。若父母不受不殺等。子能受不殺等。是名勝生子。云何下生子。若子父母不受不殺等。子亦不能受不殺等。是名下生子。

Furthermore, the Saṃyuktāgama says: At that time, the Bhagavat addressed the bhikṣus: 'There are three kinds of sons. What are the three? There is the son who follows birth; there is the son who excels birth; there is the son who is inferior to birth. What is the son who follows birth? It refers to when a son's parents do not kill, do not steal, do not engage in sexual misconduct, do not lie, and do not drink alcohol, and the son likewise follows and learns non-killing and the rest. This is called the son who follows birth. What is the son who excels birth? If the parents do not observe non-killing and the rest, but the son can observe non-killing and the rest, this is called the son who excels birth. What is the son who is inferior to birth? If a son's parents do not observe non-killing and the rest, and the son also cannot observe non-killing and the rest, this is called the son who is inferior to birth.'
