A lotus pond near Rájagaha.
The Samyutta Nikaya mentions the Buddha as relating the story of a man who went to Sumágadhá with the thought, "I will speculate about the world." He saw an army, with its four divisions, enter a lotus stalk. He then thought he must be mad and told everyone so. The Buddha explained that what the man had seen was real; it was an Asura army, fleeing from the devas in panic, through a lotus stalk (S.v.447f.; cf. Rámáyana i.34).
Near the pond was the Moranivápa, and within walking distance was the Paribbájakáráma in Queen Udumbariká's park. The Buddha was walking about in the open air near Sumágadhá, just before he preached the Udumbarikasíhanáda Sutta. D.iii.40.
