"'"Vasishtha continued, 'Hear once more, O regenerate Rishi, as I discourse upon it, the pre-eminence of gold, O foremost of all wielders of weapons. I heard this formerly in the Purana, O son of Bhrigu's race. I represent the speech of Prajapati himself. After the wedding was over of the illustrious and high-souled Rudra armed with the trident, O son of Bhrigu's race, with the goddess who became his spouse, on the breast of that foremost of mountains, viz., Himavat, the illustrious and high-souled deity wished to unite himself with the goddess. Thereupon all the deities, penetrated with anxiety, approached Rudra. Bending their heads with reverence and gratifying Mahadeva and his boon giving spouse Uma, both of whom were seated together, they addressed Rudra, O perpetuator of Bhrigu's race, saying, "This union, O illustrious and sinless one, of thine with the goddess, is a union of one endued with penances with another of penances as severe! Verily, it is the union, O lord, of one possessed of very great energy with another whose energy is scarcely less! Thou, O illustrious one, art of energy that is irresistible. The goddess Uma, also is possessed of energy that is equally irresistible. The offspring that will result from a union like this, will, without doubt, O illustrious deity, be endued with very great might. Verily, O puissant lord, that offspring will consume all things in the three worlds without leaving a remnant. Do thou then, O lord of all the universe, O thou of large eyes, grant unto these deities prostrated before thee, a boon from desire of benefiting the three worlds! Do thou, O puissant one, restrain this high energy of thine which may become the seed of offspring. Verily, that energy is the essence of all forces in the three worlds. Ye two, by an act of congress, are sure to scorch the universe! The offspring that will be born of you two will certainly be able to afflict the deities!
