Someone once said that we as humans are the eyes of the universe. We are as much a part of the universe as a star or planet, in fact even better, we are the part of the cosmos that is capable of thought. We think and feel on its behalf. We are the universe experiencing itself.
Unlike our siblings, the stars, we are bound to time. We are cursed one day to die. However, this is only more motivation for us to live this fleeting moment to its uttermost. If we do not live a life full of experiences we have failed ourselves and the universe.
We are the eyes and eyes are meant to see, we have been bestowed with life and thus must live. In a galaxy filled with cold we must be the warmth.
