When one ponders life outside of the context of religion, it becomes harder to justify. If we are just small creatures living on a rock and then, if we are fortunate, disappearing some 80 years later, it is easier to fall into nihilistic thinking and despair and yet many of us find great joy in the daily experiences of life.
I find comfort sometimes in stepping away from what I am doing and observe it from higher up. Imagine hovering several kilometers in altitude over the earth and pondering how meaningless much of what goes on here actually is. It is in that moment that we would find perspective and come to realize that much of what occupies our attention is just filler and otherwise wasted time doing things to avoid reflecting on our own mortality. But it is specifically in this mindset that we find the greatest joy because we then come to free ourselves from the things that do not have real value. We can better prioritize because we have gained insight into what brings life greater meaning which often involve no material things to speak of.
Even if we do not possess all the answers there are clues hidden in the everyday that warm our hearts and we have all experienced them. These may be small hints of a bigger picture that we cannot see with our limited minds and they are often enough to allow us to go forward when the next set of boring tasks make us lose focus.
They are like little windows into the divine which promise of something more.
