In which belief system is karma a significant concept influencing one's future life?

Karma is a significant concept in Hinduism as it refers to the law of cause and effect, where a person's actions in this life directly influence their future lives. In Hindu belief, the actions taken in one's current life can result in virtues or vices that shape the soul's journey through cycles of birth, death, and rebirth (samsara). This understanding of karma encourages individuals to perform good deeds and adhere to dharma (moral and ethical duties) to promote positive outcomes not only in this life but also in future lives. While other belief systems may acknowledge similar ideas, they do not have karma as a central tenet with the same implications on the cycle of reincarnation as in Hinduism.
