PISHACHAS There are millions of Jakhyas (Yakshas), Kinnaras and Pisachas (Pishachas). (Gauri Sukhmani M. 5, p. 276) Pishachas are friends and evil spirits. Vedas consider them lower than Rakshasas. They hare ill-natured spiteful and mischievous beings. It is said that they were created by Brahma alongwith other demons. They are said to haunt the earth and inhabit the forests. Sometimes the aborigines and wild tribes are also called Pishachas.
