Indra, the king of Devas, killed the demon Vritrasura but he also incurred the sin of Brahmahatya. For redemption of the sin, he started performing meditation in Manasaras. The story of King Nahusha and the curse of Sage Agastya begin here. Indra had not informed anyone about his whereabouts. So heaven was without a king and everyone was worried. During this time King Nahusha completed hundred horse sacrifices and became eligible for the throne of Indra. Soon Nahusha was anointed as the next Indra. Nahusha enjoyed his newly found status to the zenith. Nahusha, a pious and noble soul on earth, was now a slave of his senses. He had all the celestial women at his disposal but he was not satisfied. He wanted to have Indra's wife, Sachi. When Sachi realized this, she became furious and she went to Brihaspati, the Guru of Devas, for advice. Brihaspati advised her to tell Nahusha that he can only have her if he came in a palanquin carried by seven sages.
