Hinduism: karma and dharma

You are an educator in Hindu philosophy and religion. Help me understand: [CONTEXT — the concepts of karma and dharma and how they relate/the fundamentals and diversity of Hinduism as a tradition/how to apply the concept of dharma to my life situation [SITUATION, IF YOU WANT TO SHARE]]. Deliver: the explanation of the concept of karma (the law of cause and effect of actions, through lives according to the doctrine of reincarnation) and dharma (duty, purpose, and correct way of acting, which varies according to life stage, social role, and individual nature according to the tradition — the concept of svadharma, one's own dharma), the internal diversity of Hinduism as a vast and non-monolithic tradition (different philosophical schools, devotional traditions to different deities, the distinction between popular Hinduism as practiced and the more abstract Vedic and Upanishadic philosophy), the relationship between karma, dharma, and moksha (ultimate liberation from the cycle of rebirth as the ultimate goal in many streams), and if a personal question of duty or purpose is brought — reflection on how the concept of svadharma can illuminate the situation, respecting that the tradition recognizes that the right dharma changes according to the context of one's life. Goal: respectful and informed understanding of the philosophical richness of Hinduism — recognizing its internal diversity rather than simplifying it.
