Indeed, that snake of seven heads and vast body, of sharp fangs and virulent poison, of large neck and the masculine sex, was twined round with the cord that served as its bowstring. And there was a shaft whose splendour looked like that of the sun or of the fire that appears at the end of the Yuga. Verily, that shaft was the excellent Pasupata that mighty and terrible weapon, which is without a second, indescribable for its power, and capable of striking every creature with fear. Of vast proportions, it seemed to constantly vomit sparks of fire. Possessed of one foot, of large teeth, and a thousand heads and thousand Stomachs, it has a thousand arms, a thousand tongues, and a thousand eyes. Indeed, it seemed to continually vomit fire. O thou of mighty arms, that weapon is superior to the Brahma, the Narayana, the Aindra, the Agneya, and the Varuna weapons. Verily, it is capable of neutralising every other weapon in the universe. It was with that weapon that the illustrious Mahadeva had in days of yore, burnt and consumed in a moment the triple city of the Asuras. With the greatest ease, O Govinda, Mahadeva, using that single arrow, achieved that feat. That weapon, shot by Mahadeva's arms, can, without doubt consume in half the time taken up by a twinkling of the eyes the entire universe with all its mobile and immobile creatures. In the universe there is no being including even Brahma and Vishnu and the deities, that are incapable of being slain by that weapon.
