“For the sake of wealth there're 7 types of commerce: perfume trade, moneylending, cow related trade & activities, serving known customers (because he wouldn't use foul language), false pricing of products (buying at less & selling at higher prices), underweighing, importing. Of all saleable products, perfume trade is the best, which is incomparable to gold etc; and which can be sold for 100 times its cost”
