My Dad had a dying process that took a few months. He worried quite a bit that he had done nothing with his life. Nothing big. Nothing that stood out. When word got out that he was terminally ill however, letters started pouring in from people all over the world (he worked in several countries before he retired) who recounted the two most important things about him: his kindness and his impeccable graciousness and manners. I don't think he ever quite saw that this was in fact the "big" thing that he had done. One letter was from a woman that was remembering that he hired her at 19 for her first job. She was nervous and suffering from a lack of self esteem and she remembered how my Dad instantly put her at ease, boosted her confidence (and gave her a job!). She credited him with setting her life on a course that had since taken her to several countries and given her a career that she loved. One act of kindness>large result. There were many letters like this.
In addition to his kindness, my father also loved his children unconditionally. This is different from perfectly. He was human and we all had our struggles, but in the end, he gave us what every person needs to thrive: someone that has faith in you. Because my father did what is simply expected of a parent (love your children unconditionally) he gave three people (his kids) the knowledge and example of what that means. We take that knowledge and put it into practice in our own lives. It does not make the world perfect, it does not save the world instantaneously (indeed, it could not save my own son) but it matters. It improves life.
Kindness and respect, whether in small daily acts or huge sacrifices, are what give meaning to a life. We live in a world that is becoming increasingly disconnected, rude, polarized, self-centered and greedy---and because of our numbers the toll this is taking on each other, other species and the planet can feel overwhelming. It is good to remember that we are healing the world every time we align ourselves with compassion. It is contagious. It can be spread and it is in fact revolutionary to do so.
