Brahma said:—O Devas! This Tarakâsura is not destined to die at the hands of any one in the world His destroyer has not yet been born in the three worlds That demon has been granted a boon by virtue of his asceticism but I have skilfully managed it He is a most powerful Lord and can consume all the three worlds He sought his death at the hands of a seven days' old infant. This babe illustrious as the Sun, will be born of Śaṅkara and when he will be of seven days, he will kill the Demon The son of Śiva shining like the sun will be the annihilator of Târakâsura At present, Lord Śiva is without any consort I spoke to you before of the Devî with raised hands This Goddess will be the daughter of the Himâlaya Her hands will always be raised to grant boons to others, and the son born of Her by Śiva like a fire from pieces of wood, will destroy the demon king I have formed the plan The demon has yet to enjoy a little store of his splendour, you should, therefore, be patient for some time to come—47 54
