Final answer:
In both Hinduism and Buddhism, the virtue of a person's life impacts their afterlife through the concepts of karma and reincarnation, leading towards ultimate liberation - Moksha in Hinduism and nirvana in Buddhism.
Step-by-step explanation:
According to both Hinduism and Buddhism, the extent to which a person has lived a virtuous life determines the quality of his or her afterlife. This concept in both religions is deeply intertwined with the ideas of karma and reincarnation. In Hinduism, karma is the sum of a person's actions in this and previous states of existence, viewed as deciding their fate in future existences. Good karma can lead to being born into a higher caste or a more conscious lifeform, whereas bad karma can result in a lower form of life. The end goal is reaching Moksha, where the soul is released from the cycle. In Buddhism, there is no permanent soul, but karma still affects the rebirth cycle with virtuous actions leading to better rebirth circumstances. The ultimate goal here is achieving nirvana, a state of liberation and freedom from suffering.
