Mahabharata Aswamedha Parva Chapter 10:2

Mahabharata Aswamedha Parva (Aswamedhika Parva) Chapter 10:2 Samvarta said, 'O lion among kings, thy fear of Sakra will soon be dispelled, and I shall soon remove this terrible pain by means of my magic lore (incantation); be calm and have no fear of being overpowered by Indra. Thou hast nothing to fear from the god of a hundred sacrifices. I shall use my staying charms, O king, and the weapons of all the gods will avail them not. Let the lightening flash in all the directions of space, and the winds entering into the clouds pour down the showers amid the forests and the waters deluge the heavens and the flashes of lightning that are seen will avail not. Thou hast nothing to fear, let Vasava pour down the rains and blast his terrific thunderbolt where he will, floating among the watery masses (clouds) for thy destruction, for the god Vahnni (Agni) will protect thee in every way, and make thee attain all the objects of thy desire.' Marutta said, 'This appalling crash of the thunderbolt together with the howling of the winds, seem terrible to my ears and my heart is afflicted again and again, O Brahmana, and my peace of mind is gone at present.' Samvarta said, 'O king, the fear in thy mind from this terrible thunderbolt will leave thee presently. I shall dispel the thunder by the aid of the winds, and setting aside all fear from thy mind, do thou accept a boon from me according to thy heart's desire, and I shall accomplish it for thee.' Marutta said, 'I desire, O Brahmana, that Indra all on a sudden should come in person at this sacrifice, and accept the oblation offered to him, and that all the other gods also come and take their own shares of the offerings and accept the libations of Soma offered to them.' Samvarta said, 'I have by the power of my incantations attracted Indra in person to this sacrifice. Behold, O monarch, Indra coming with his horses, and worshipped by the other gods hastening to this sacrifice.' Then the lord of the Devas attended by the other gods and riding in his chariot drawn by the most excellent steeds, approached the sacrificial altar of that son of Avikshit and drank the Soma libations of that unrivalled monarch. And king Marutta with his priest rose to receive Indra coming with the host of gods and well-pleased in mind, he welcomed the lord of the Devas with due and foremost honours according to the Sastras. Samvarta said, 'Welcome to thee, O Indra, by thy presence here, O learned one, this sacrifice has been made grand. O slayer of Vala and Vritra, do thou again quaff this Soma juice produced by me today.' Marutta said, 'Do thou look with kindness upon me, I bow unto thee, O Indra, by thy presence, my sacrifice has been perfected, and my life too blessed with good results. O Surendra, this excellent Brahmana, the younger brother of Vrihaspati is engaged in performing my sacrifices.'
