Bhikkhu Bodhi, an American Theravada Buddhist monk wrote an article called The Search for Security on a website called Access to Insight. This is from the first paragraph:
“We only feel at ease when we are sealed off from manifest danger, comfortably at home with ourselves and with our world, snugly tucked into familiar territory where everything seems friendly and dependable.”
Probably the best perspective on this, as well as one of the most intelligent things anyone has ever said is by Helen Keller:
“Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure, or nothing.”
You cannot win, if you do not play.
