There is one specific idea which I have found to be incredibly useful when confronting and accepting various forms of pain, specifically the pains and anxieties of everyday life: the concept of sub specie aeternatis. This is the idea of viewing humanity, and more specifically your very own life, in the time period of all history and of the future as well. The span of our own lives is utterly negligible if we look at the big picture-that the universe has existed for millions and millions of years, and will probably continue to do so for a long time. Looking at life like this, all the pettiness is removed. When we are reminded of our own insignificance and the perhaps completely meaningless nature of our troubles, w may be able to detach ourselves from our own trouble, thereby gaining power and control over them, rather than the other way around. It is a matter of recognising how arbitrary everything can seem, merely by looking at the bigger picture. It may seem simple, but its effect may be astounding.
