Parkaya Pravesh or entering the body of any other person is considered to be one of the most powerful Shakti or Supernatural Power that can be gained by a practitioner of Tantra Shastra. Parkaya Pravesh is mostly considered to be an Aghor Panth Tantra and even though most Sadhaks of the Aghor Panth strive to gain this supernatural power, only a handful of them manage to succeed.
