If you have money, then spend it for Krsna, as much as you can. Then if you don’t spend, if you think, “Krsna wants patram puspam; the money I shall keep in the bank for my pleasure,” then Krsna will cheat you also. If you want to cheat Krsna, Krsna is the greatest cheater. Then you’ll be cheated. Don’t be cheater. Simply, fervently, very honestly obey the orders of Krsna.
