By Swami Harshananda
Raghu was a famous king of the Suryavanśa and a distinguished scion of the Ikṣvāku race. He was the great-grandfather of Śri Rāma. After him, the race itself came to be known as Raghuvaṅśa.
After conquering the whole world, Raghu performed the Viśvajit sacrifice wherein he gave away all his wealth and possessions. When the sacrifice was over, the sage Kautsa, a disciple of Viśvāmitra, approached him for a very heavy gurudakṣiṇā. Seeing the indigent circumstances of the king himself, Kautsa was about to depart. However, Raghu dissuaded him and started preparing to attack Kubera, the god of wealth, who rained gold coins on Ayodhyā, the capital city. Kautsa took what he wanted and left after blessing the king profusely.
