When you are in a Dharma discussion, each word you say should be Relevant to the Essence and to the Circumstance. Please speak in accord with the teachings of impermanence, nonself, and nirvana; and speak directly to those present, taking into account their experience, their knowledge, and their insight. There may be things you consider important but cannot say to this particular group. The Two Relevances require you to speak with skillfulness, tolerance, and care.
