If ownership were worldly, prescribing punishment for those who acquire wealth even by means of sacrificing and the like from one who takes what is not given would be untenable. Furthermore, if ownership were worldly, one would not say, 'My property has been stolen by him,' because ownership would belong solely to the thief; otherwise, [if one argues that] another's property was stolen by him, hence it is not the thief's property, then, just like the intrinsic nature of gold, silver, and the like, there would be no doubt whether it is this person's property or another person's property. Therefore, ownership is knowable solely through sacred tradition.
