At one time the tenants of an estate became unruly. The landlord had to send Golak Choudhury, who was a ruffian. He was such a hard administrator that the tenants trembled at the very mention of the name.

There is need for everything. Once Sita said to her husband: "Rama, it would be grand if every house in Ayodhya were a mansion! I find many houses are old and dilapidated." "But, my dear," said Rama, "If all the houses were beautiful ones, what would the masons do?" God has created all kinds of things. He has created good trees and poisonous plants and weeds as well. Among the animals there are good, bad, and all kinds of creatures - tigers, lions, snakes, and so on.
