The four components in the “Ceil­ing on Desires” programme are: Curb on excessive talk, curb on excessive desires and expenditure, control of consumption of food, and check on waste of energy. You need some essential commodities for sustenance, and you should not aspire for more. Only if air is available in sufficient quantity will it be comfortable. If it is excessive and there is a gale, you will feel uncomfortable. When you are thirsty, you can consume only a limited quantity of water needed for the sustenance of the body; you can’t drink the entire water of the River Ganga. Your eyes automatically close when they happen to see a flash of lightning because they can’t withstand such high illumination. Therefore there must be a limit to everything, including desires.(Divine Discourse, Jan 19, 1983.)
