In Hinduism the soul (atman) is immortal while the body is not. The world we live in is a dream, and illusion and the result of being trapped in the samsara (the wheel of reincarnation) is a result of ignorance towards the nature of existence and this is linked to the action of karma. Every action has a reaction force that will determine one’s next incarnation. When one is reborn again and again, we become dissatisfied and begin to seek higher forms of joy through spiritual experience. After spiritual practice (sadhana), a person realizes that the true “self” is the immortal soul rather than the body or the ego all desires for the pleasures of the world will vanish since they will seem insipid compared to spiritual ānanda (happines). When the soul has completed all the desire it required, the person will not be born again.
When the cycle of rebirth comes to an end, the person is said to have attained it’s liberation (moksha). Some understand that when this is achieved, one will spend eternity in the perfect peace and happiness of the realization that all existence is ONE, Brahman of which the soul will be part of. Dvaita schools perform worship with the goal of spending eternity in a spiritual world or heaven (loka) in the blessed company of the Supreme Being.
