Nothing and no one is isolated.
“Nothing ever exists entirely alone; everything is in relation to everything else.” Buddha
It is when we remember that nothing in our universe is not connected to something else. That raindrop is affected by the atmosphere it falls though, if there is a wind then it will be driven at an angle.Before it fell t was part of a cloud, before that it was water vapor that collected around a dust particle. Once it lands, it it lands on more water it will become an indistinguishable part of the greater mass. If it lands on a leave, it may stay there for a while or roll off.
As people we are no different then the rain. We meet new people everyday on our journey. Some will be a brief face in a crowd, never to be seen again. Others may be a recurring vision, such as the person we see on our commute via bus or train every workday. A few will be people we interact with, and fewer still the ones that become important to us. Every single one of us alive. all those who proceeding us, or those that have yet to be born will have this same experience. Yet no two will interact with the exact same group of people. How we interact with these people is up to us. Are we a happy person that draws others to make eye contact, perhaps even smile or say hello? Or are we walking around looking like a grouch, discouraging any who look our direction from approaching us? How are you greeting the world today, with love and compassion, indifference or hostility? It starts with how we control our thoughts.
