Conduct is based on the understanding of karma.
Right conduct means to ensure that actions, whether through body or speech, are not influenced by disturbing emotions. If actions are biased, negative karma is created. For example, we bring harm to people and possibly even kill others, if we let ourselves be influenced by anger. With the motivation of anger, a great deal of negativity and ill will arises. Right conduct means to be free of those influences and instead, let our actions be guided by positive qualities like compassion.
