Final answer:
In the Hindu caste system, earning good karma during a person's life is the only way to move up in the caste system.
Step-by-step explanation:
In the Hindu caste system, the only way to move up in the caste system was to earn good karma during your life so you can be reincarnated higher up. According to Hindu beliefs, positive and upright actions would draw a person closer to God and result in a higher rebirth in the next life. Conversely, negative actions would take a person farther from God and lead to a lower form of worldly life or caste level.
