The Dharma Wheel, or Dharmachakra, primarily symbolizes the concept of dharma in Hinduism, which is the law of righteousness, moral order, and duty. However, among the options you've provided, the most closely related concepts to Hindu beliefs, particularly in the context of the cycle of life, would be reincarnation.
If we're recognizing the broad themes associated with Hindu philosophy, moksha—liberation from the cycle of birth and rebirth—is another significant idea.
Given the focus on the cycle of life and rebirth, I would select reincarnation as the most appropriate answer in this context.
