Past life regression is typically undertaken either in pursuit of a spiritual experience or in a psychotherapeutic setting. In ancient Indian literature, the Upanishads mention past-life regression, but the Yoga Sutras of Patañjali discuss the concept in greater detail. Written during the 2nd century BC, the Hindu scholar Patañjali discussed the idea of the soul becoming burdened with an accumulation of impressions as part of the karma from previous lives.

Maharishi Patañjali called the process of past-life regression prati-prasav (literally "reverse birthing"), and saw it as addressing current problems through memories of past lives. Some types of yoga continue to use prati-prasav as a practice.

Past Life Regression is valuable and the only source for clearing/healing traumatic experiences in prior lifetimes, which otherwise holds us back from full actualisation in this life, and/or is causing distress. Additional benefits are activating creativity or a valuable talent that was actively expressed before but has remained latent or unrecognised in this life.

Benefits of Past Life Regression include the following:

1) Healing overt acts (the past-life self as the perpetrator rather than the victim).

2) Contacting creativity
