That's the whole idea of Hinduism, is follow your dharma, which is dictated by your karma, so you can achieve moksha and free your soul from earth to be connected with the one, with the eternal. Now certainly Hinduism is practiced in many different forms. Much of it sometimes is a family tradition. Other times Hindus seek out their own personal path and there's lots of different ways to practice that. Now of course there's other commonalities in Hinduism itself. They believe that the rivers of the Ganges are sacred. They cleanse their souls by bathing in it.
