What is Karma? What is Dharma?

Why is it that we sometimes have good days and sometimes not as good ones? Is it the external circumstances that cause this or is it the internal circumstances that cause the good or less good days? Even if Pari comes from a tradition of immediate welcoming what is knocking on the day, he shares the differences between Karma as the law of cause and effect based on the example of gravity and Dharma, which can be defined as the universal law of serving us. The two do not contradict each other, although they are different in their approach and yet it is our inner intelligence, which guides us through imprints and unconscious patterns.
