At one time the Buddha was staying near Rājagaha in the Bamboo Grove, the squirrels’ feeding ground. There the Buddha addressed the mendicants: “Once upon a time, mendicants, a certain person left Rājagaha, thinking ‘I’ll speculate about the world.’ They went to the Sumāgadhā lotus pond and sat down on the bank speculating about the world. Then that person saw an army of four divisions enter a lotus stalk. When he saw this he thought, ‘I’ve gone mad, really, I’ve lost my mind! I’m seeing things that don’t exist in the world.’
