What happens to ones soul when undergoing reincarnation?

In the belief system of reincarnation, the soul undergoes a cycle of birth, death, and rebirth, moving from one body to another based on the karma accumulated in previous lives. Each incarnation provides opportunities for the soul to learn, grow, and evolve spiritually. Ultimately, the goal is to achieve enlightenment or liberation, breaking free from the cycle of rebirth and merging back with the divine or universal consciousness. The specifics can vary widely among different cultures and religions.
