Hinduism
Beliefs and practices pertaining to the practice of exorcism are prominently connected with Hindus. Of the four Vedas (holy books of the Hindus), the Atharva Veda is said to contain the secrets related to magic and alchemy. The basic means of exorcism are the mantra and the yajna used in both Vedic and Tantric traditions. Vaishnava traditions also employ a recitation of names of Narasimha and reading scriptures, notably the Bhagavata Purana aloud.
According to Gita Mahatmya of Padma Purana, reading the 3rd, 7th and 9th chapter of Bhagavad Gita and mentally offering the result to departed persons helps them to get released from their ghostly situation. Kirtan, continuous playing of mantras, keeping scriptures and holy pictures of the deities (Shiva, Vishnu, Brahma, Shakti, etc.) (especially of Narasimha) in the house, burning incense offered during a Puja, sprinkling water from holy rivers, and blowing conches used in puja are other effective practices.
The main puranic resource on ghost and death-related information is Garuda Purana.
A complete description of birth and death and also about the human soul are explained in Katō Upanishad, a part of Yajur Veda. A summary of this is also available as a separate scripture called Kāttakaṃ.
