That in a short while you will be nobody and nowhere; and the same of all that you now see and all who are now alive. It is the nature of all things to change, to perish and be transformed, so that in succession different things can come to be.
That all is as thinking makes it so - and you control your thinking. So remove your judgements whenever you wish and then there is calm - as the sailor rounding the cape finds smooth water and the welcome of a waveless bay.
Although not easy, we all should do our best to ensure every action we take has a goal; and furthermore, the goal of all our action should be established with the end goal being: the common good.
Always keep in mind that your life is short at best. And at worst, it could be lost so easily - by illness, accident or randomly. Nature loves to change and as we humans are a part of nature, we too must change and eventually return to the basic elements.
Today, a lot of kids use the word "triggered" when describing someone who is easily upset. An example would be if students are being somewhat rowdy and loud and they don't immediately listen to a teachers urging for them to settle down. A student might then do something intentional to be disruptive, at which point the teacher becomes very upset - she would be "triggered." The teacher does not need to get angry - she can control her thinking and therefore her reaction. The same can be applied to each of us in a many situations. We can control our judgement and reaction to any situation. The key is to practice!
