The obligation is ‘obeying the Shasana’ (Law). When a stray dog enters the house, moves into the kitchen, guzzles the food kept ready for lunch and runs to breaking a few dishes and cups, it will not be dragged into court and forced to pay compensation. But, when a man does the same, the law takes hold of him and binds him. When a pig enters a field and damages the crop, no one arrests it and claims payment for the loss inflicted.
Animals have no moral responsibility to leave alone the property of others. They are not human beings who ought to control their greed and their hatred. When men are moved into inhuman ways, the law has to restrain and reform them. (SSS Vol.16, pp. 111-112)
