Would you prefer to have hope there will be a cure for your tinnitus sometime in your lifetime?
Do you mean that it would be easier to deal with tinnitus if we had hope for a cure?
I think just by examining what goes on around us, in the world and the universe, I cant help but to think that hope is a byproduct of us being human and alive. We have made so many discoveries, both intended and unintended, from medicine to engineering to physics. It may only take us one more discovery about tinnitus to get a cure or one more accident.
As far as what makes be spiritual, Im going to steal from Neil deGrasse Tyson as he explains how i feel far better than i ever could.
"The most astounding fact, the most astounding fact is the knowledge, that the atoms comprise life on earth; the atoms that pick up the human body, are traceable to the crucibles, that cooked light elements into heavy elements in their core, under extreme temperatures and pressures. These stars, the high mass ones among them, went unstable in their later years. They collapsed and then exploded, scattering their enriched guts, across the galaxy. Guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds, that condense, collapse, form the next generation of solar systems stars with orbiting planets and those planets now have ingredients for life itself. So that when I look up at the night sky, and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up. Many people feel small, because they're small and the universe is big, but I feel big, because my atoms, came from those stars. There is a level of connectivity. That's really what you want in life, you want to feel connected, you want to feel relevant. You want to feel like your a participant in the goings on of activities and events around you. That's precisely what we are, just by being alive. "
