My Guru Mahārāja used to say that if one is inclined to collect money by showing Deity, it is better to become a sweeper in the street. It is better to become a sweeper in the street, because he's earning his livelihood honestly.
And this man who is keeping a temple and doing all nonsense, simply by showing Deity, collecting some money, this class of men, they're most sinful. You cannot do so. You cannot take other's money. You'll be debtor.
(Prabhupada lecture Bg As It Is 9.2 Calcutta, March 8th 1972)
