Charles F. Glassman said this quote

Take a moment, right now, and consider the enormity of activity going on inside of you – from the billions of cells to the even more billions of microscopic organisms. And in that same moment consider the enormity of activity in the oceans, the forests, the jungles, the earth below your feet, right now. And before you take your next breath, consider what might be going on in the outer regions of the universe. Finally, ask yourself, am I really in a position to discount possibilities beyond the limits of my conscious experience?
