You no doubt have heard, "this too shall pass..." Well, that really gets to the guts of what this skill means. Nothing is permanent - nothing. As painful as something is: an experience, a moment, a relationship, a trial - at some point it will be different. Something will give way to something else. It may seem far fetched to consider, but even the most lengthy trials must come to end in some fashion, at some point. So take a deep breath and "Obey the Law of Impermanence" When we truly obey that law, we will allow a sense of peace to come over us because we know, this too shall pass!
