3.23

壞生種戒第十一　制意如上。犯緣亦同。此戒不別有緣。舉前房戒緣中。比丘自斫樹以為緣起。

The eleventh precept: destroying living seeds.
The intention behind its institution is as above, and the conditions for the offense are also the same. This precept has no separate origin story; it was formulated based on the origin story in the preceding precept on dwellings, where a bhikṣu felled a tree himself.
