Nothing very subtle about the closing paragraph:
When Zen Buddhist masters ignore the law of cause and effect and fail to live ethically according to the precepts, they have manifested into negative actions. They then create suffering not only for themselves but also for others, for as I mentioned earlier, “karma” means “action.” The law of karma is: positive actions have positive results, negative actions have negative results, neutral actions have neutral results. No one is above this law, no matter how long one has practiced or how deep their understanding.

The term first came into use at the Protestant Reformation, when it was employed by Martin Luther to designate the teachings of Johannes Agricola and his sectaries, who, pushing a mistaken and perverted interpretation of the Reformer's doctrine of justification by faith alone to a far-reaching but logical conclusion, asserted that, as good works do not promote salvation, so neither do evil works hinder it; and, as all Christians are necessarily sanctified by their very vocation and profession, so as justified Christians, they are incapable of losing their spiritual holiness, justification, and final salvation by any act of disobedience to, or even by any direct violation of the law of God.
