Only then is it right speech. Otherwise it again becomes the futile talk drawn from some book or some teacher. Until it becomes a part of one' s life, one does not gain from it. Therefore samma vaca should be actual right speech. Samma-kammanto means right action, purity of physical action.
Every action arises in the mind first and proceeding further, becomes a vocal action.
When it proceeds still further, it manifests itself as a physical action. This should also be right, correct, perfected. It should not cause harm to others, disturb the peace and harmony of others, or cause unhappiness to others. One should make right action a part of one's life, by abstaining from killing, from stealing, from sexual misconduct, from taking any kind of intoxicant. If it is known from experience that one does not perform such actions at all, then it is right action.
