In the stage corresponding to sleep with dreams (svapna) the psycho-mental is detached from the objective world and engaged in a virtual world, a mere projection of the real one.
Other Eastern religions, such as Buddhism and Taoism, take salvation as an illumination, meaning the discovery of and conformity of oneself with an eternal law that governs existence.
Dualistic religions, which state that two opposed forces of good and evil rule our world, see salvation as a return to an initial angelic state, from which humans have fallen into a physical body.
Here is how the worshippers of Indra express their longing for personal immortality: Make me immortal in that realm where movement is accordant to wish, In the third region, the third heaven of heavens, where the worlds are resplendent. (Rig Veda 9,113,8-9) Yama, the god of death, is sovereign over the souls of the dead and is at the same time the one who receives the offerings of the family for the benefit of the departed.
He casts the wicked into an eternal dark prison from which they can never escape (Rig Veda 7,104,3; 17).
In this article we will analyze more closely these alternatives, trying to understand to what extent they can still be compatible with each other.

The liberation of atman from the chain of reincarnation can be attained only during a human existence, so we are in a privileged stage of spiritual evolution. They are in a stage of reaping one’s positive merits during a lifetime, as animals are the opposite, the stage of reaping bad merits.

It is not only useless, but it fuels ignorance and the gods encourage it: Now, if a man worships another deity, thinking, "He is one and I am another," he does not know. As many animals serve a man, so does each man serve the gods.
Even if one animal is taken away, it causes anguish to the owner; how much more so when many are taken away!
However, the Upanishads have replaced completely this early view of salvation and eternal life with their pantheistic view.
