Reincarnation is the religious or philosophical concept that the soul or spirit, after biological death, begins a new life in a new body that may be human, animal or spiritual depending on the moral quality of the previous life's actions. This doctrine is a central tenet of the Indian religions.
In recent decades, many Europeans and North Americans have developed an interest in reincarnation.
Reincarnation – known as Punarjanma – it is one of the core beliefs of Hinduism that is generally accepted by many of its practitioners.
Reincarnation is the natural process of birth, death and rebirth. Hindus believe that the Jiva or Atman (soul) is intrinsically pure. Howevever, because of the layers of I-ness and My-ness, the jiva goes through transmigration in the cycle of births and deaths. Death destroys the physical body, but not the jiva. The jiva is eternal. It takes on another body with respect to its karmas. Every karma produces a result which must be experienced either in this or some future life. As long as the jiva is enveloped in ignorance, it remains attached to material desires and subject to the cycles of births and deaths (Samsara).
There is no permanent heaven or hell in Hinduism. After services in the afterlife, the jiva enters the karma and rebirth system, reborn as an animal, a human or a divinity. This reincarnation continues until mokṣa, the final release, is gained.
We believe the self or soul (atman) repeatedly takes on a physical body.
The Bhagavad Gita states;
Never was there a time when I did not exist, nor you, nor all these kings; nor in the future shall any of us cease to be. As the embodied soul continuously passes, in this body, from childhood to youth to old age, the soul similarly passes into another body at death. A sober person is not bewildered by such a change. (2:12-13)
and,
Worn-out garments are shed by the body; Worn-out bodies are shed by the dweller within the body. New bodies are donned by the dweller, like garments.
Sharing the perspective of Vedanta philosophy on PLR…. This is an Excerpt From: Abhedānanda, Swāmī. “Five Lectures on Reincarnation.” iBooks. :
“Those who wish to satisfy the idle curiosity of their minds may spend their energy by trying to recollect their past lives. But I think it will be much more helpful to us if we devote our time and energy in moulding our future and in trying to be better than we are now, because the recollection of our former condition would only force us to make a bad use of the present.
How unhappy he must be who knows that the wicked deeds of his past life will surely react on him and will bring distress, misery, unhappiness or suffering within a few days or a few months. Such a man would be so restless and unhappy that he would not be able to do any work properly; he would constantly think in what form misery would appear to him. He would not be able to eat or even sleep. He would be most miserable. Therefore we ought to regard it as a great blessing that we do not recollect our past lives and past deeds.
Vedanta says, do not waste your valuable time in thinking of your past lives, do not look backward during the tiresome journey “through the different stages of evolution, always look forward and try first to attain to the highest point of spiritual development; then if you want to know your past lives you will recollect them all. Nothing “will remain unknown to you, the Knower of the universe. When the all-knowing Divine Self will manifest through you, time and space will vanish and past and future will be changed into the eternal present. Then you will say as Sri Krishna said to Arjuna, in the “Bhagavad Gita:” “Both you and I have passed through many lives; you do not recollect any, but I know them all.” (Ch. iv., 5.)”
