the essence of nirodha is liberation

You asked about our thoughts on the translation "appeasement". Appeasement is a good translation in some contexts but as Dave said, sometimes the word nirodha is best translated as non-arising. It did not occur to me before but wherever a complete lack of something is meant by nirodha, the word appeasement can get misunderstood. The best translation depends on the context imo.
