You should not expend more than your income.
So kāmam, yes, what is that? Annād, annād bhavanti bhūtāni. Bhūtāni means embodied, those who have taken, accepted, the living entities. They live by eating anna, either animal or human being. You require anna. Produce foodgrains. Foodgrains or grass or anything, as the animals eat and man eat, you must produce. And that production is there on the ground, not you factory. Not in the Birmingham factories. There are many factories in Birmingham? You cannot produce foodgrains there. Therefore it is said, annād bhavanti bhūtāni.
