The evil witches known as Ḍākinīs, Yātudhānīs and Kuṣmāṇḍas are the greatest enemies of children, and the evil spirits like Bhūtas, Pretas, Piśācas, Yakṣas, Rākṣasas and Vināyakas, as well as witches like Koṭarā, Revatī, Jyeṣṭhā, Pūtanā and Mātṛkā, are always ready to give trouble to the body, the life air and the senses, causing loss of memory, madness and bad dreams. Like the most experienced evil stars, they all create great disturbances, especially for children, but one can vanquish them simply by uttering Lord Viṣṇu’s name, for when Lord Viṣṇu’s name resounds, all of them become afraid and go away.
