Krsna, The Supreme Personality of Godhead

It is said that wherever the chanting of the holy name of Kṛṣṇa is done, even negligently, all bad elements—witches, ghosts and dangerous calamities—immediately disappear.

Krsna Book 6:

After consulting with his demoniac ministers, Kaṁsa instructed a witch named Pūtanā, who knew the black art of killing small children by ghastly sinful methods, to kill all kinds of children in the cities, villages and pasturing grounds. Such witches can play their black art only where there is no chanting or hearing of the holy name of Kṛṣṇa. It is said that wherever the chanting of the holy name of Kṛṣṇa is done, even negligently, all bad elements—witches, ghosts and dangerous calamities—immediately disappear. And this is certainly true of the place where the chanting of the holy name of Kṛṣṇa is done seriously—especially in Vṛndāvana when the Supreme Lord was personally present. Therefore, the doubts of Nanda Mahārāja were certainly based on affection for Kṛṣṇa. Actually there was no danger from the activities of Pūtanā, despite her powers. Such witches are called khecarī, which means they can fly in the sky. This black art of witchcraft is still practiced by some women in the remote northwestern side of India. They can transfer themselves from one place to another on the branch of an uprooted tree. Pūtanā knew this witchcraft, and therefore she is described in the Bhāgavatam as khecarī.
