Asteya covers taking what has not been given, and the commentarial extensions are commercial: adulterating goods, using false weights and measures, dealing in stolen property, smuggling, evading duties, and exploiting a shortage. Because Jains are heavily concentrated in trade, banking, jewellery and the diamond business — the Palanpuri Jain community's move into the Antwerp diamond trade from the 1960s is the most-cited modern instance — the vow has functioned as a commercial reputation and, in effect, as collateral. Historians of Indian commerce, including on the hundi bill-of-exchange networks that moved money across the subcontinent before formal banking, have noted the role of community reputation in enabling credit without enforcement, and Jain and Marwari networks are the standard examples. The community is quite clear-eyed that the ethical vow and the business advantage are entangled, and Jain business ethics is a live genre of writing within it, including sustained criticism of members who trade on the reputation without keeping the vow.
