Re: What is the significance?
Yes - that is what I mean. So each of us, each living being is significant, no matter how small. As to what all of these actions amount to in the end - in the end the earth as we see it will probably be destroyed. But between now and then, each of us can leave our (hopefully) positive imprint. It could be helping out those who need help, treating others kindly, developing friendships among nations, using less energy, etc. These are practical things one can do.
It certainly helps to believe there is a greater purpose. I am not fortunate to know what that greater purpose is for me. A friend of mine once told me that it is good to give a hand and lift someone gently when they need that gentle lift the most. The trick is to do so without letting them even know that you have helped them.
