Definition - What does Reincarnation mean?
Reincarnation (or rebirth) is the concept that the eternal soul or spirit (atman) begins a new life after the body dies. This philosophical and religious idea is central to both Buddhism and Hinduism. However, some people who do not have a religious practice also believe in reincarnation.
For those that hold reincarnation to be true, it is thought that complete realization of the Self, Truth or enlightenment through the spiritual practices of yoga, meditation and worship can liberate an individual from the cycle of reincarnation. This spiritual liberation is called moksha. The philosophical and religious concept of karma also influences reincarnation and one’s ability to be liberated from it.
Yogapedia explains Reincarnation
The concept of reincarnation hinges on the idea of an eternal soul or life force that continues into another life after biological death. Although this is a central idea to many religions, some non-religious people find the philosophical concept of reincarnation attractive and choose to prescribe to its belief.
In the spiritual practice of yoga, which is rooted in Hindu and Buddhist philosophies, reincarnation is mentioned in "The Yoga Sutras of Patanjali." The text also outline techniques for learning about past lives. Yoga itself can be a means of moving the practitioner closer to moksha, which will eventually free them from the cycle of reincarnation if they dedicate themselves to this path.
