Nahusha on Indra's Throne and Indra's Return
Source: Mahabharata, Udyoga Parva, Chapters 9–17; Vana Parva, Chapters 177–180
After slaying Vritra, the sin of *brahmahatya* — the killing of a brahmin — pressed so heavily upon Indra that he could not remain in Swarga. He hid himself, diminished and contaminated by the sin, inside the stalk of a lotus flower in a distant lake in the Himalayas, invisible to gods and men. Heaven stood empty of its king.
The three worlds could not function without governance. Brahma and the gods searched for a replacement and settled upon Nahusha, a king of exceptional virtue and power, a man whose accumulated merit seemed to justify the honor of heaven's throne. Nahusha accepted.
For a time the arrangement held. But the Mahabharata records that power altered Nahusha in the way power tends to alter those who were not born to hold it divinely. He grew arrogant. He looked upon Indra's queen, Shachi — *Indrani* — with desire and demanded that she come to him as his wife, since her husband had abandoned his throne and was presumably dead or incapacitated. Shachi refused. She went to Brihaspati for protection and sought a means to bring her true husband back.
Shachi also approached Nahusha with apparent compliance, asking only that he come to her carried in a *palanquin* borne by the great sages — the *Saptarishis* and other brahmin seers — as a mark of his supreme kingship. Nahusha, drunk on his elevation, agreed and compelled the sages to carry him. The sages bent under the weight of the palanquin with humiliation and fury. One of them — the great sage Agastya — moved slowly. Nahusha struck him with his foot and ordered him to move faster, crying out *sarpa sarpa* (go faster, or in some readings, "move, move," a word that also means serpent).
Agastya's curse fell immediately. Let Nahusha become what his word invoked — a *sarpa*, a serpent. Nahusha fell from the palanquin transformed into a great python and descended to the earth, where he would remain in that form until Yudhishthira, in the forest during the Pandavas' exile, answered the python's questions and released him.
With Nahusha removed, the gods brought Indra back. The sin of Vritra's killing had been distributed and the expiation completed. Indra was restored to Swarga, Shachi was restored to her husband, and the governance of heaven returned to its proper occupant.
The episode carries weight at multiple levels. Nahusha's fall was entirely self-generated — he was given Indra's kingdom precisely because he was virtuous, and he destroyed himself through the desire and arrogance that the throne awakened in him. Even striking a sage with his foot while being carried aloft — an act of contempt for the men who bore him — was sufficient to undo everything. The Mahabharata uses Nahusha's story to illustrate a principle it returns to repeatedly: *dharma* (cosmic-moral order) does not remain stable in the hands of those who mistake position for permission.
