The Haryaśvas, the sons of Prajāpati Dakṣa, were very well-behaved, cultured sons, but unfortunately, because of the instructions of Nārada Muni, they deviated from the order of their father. When Dakṣa heard this news, which was brought to him by Nārada Muni, he began to lament. Although he was the father of such good sons, he had lost them all. Certainly this was lamentable.
