In fact one could argue that no real Dharmic teaching
is complete if the law of karma is not accepted. Understanding the
law of karma we act in such a way to promote the good of all,
regardless of our outer beliefs or appearances of name and form.
understanding of the nature of Dharma and the law of karma must go
together. Otherwise Dharma, which means natural law, loses its
significance. Of course, many religions do not accept the law of
karma, so how can they be called Dharmas?
Generally traditions that call
themselves Dharmic, like Hinduism and Buddhism, regard religion as a
way of meditation designed to bring us to union with God or to
enlightenment, and to release from the cycle of rebirth. This could
be called the Dharmic way of spiritual development. But all
religions are not of this sort.
