Wonderful passage. Accepting the "paradoxes" of life in various aspects make us unravel a new meaning of the word "paradox". For ex: feeling pain releases pain, experiencing noise when we strive for inner silence, etc... in the grand scheme of things, we are not able to enjoy laughter without it being at the expense of sorrow - at some level... and perhaps all paradoxes go hand in hand with their counterparts.
Also, the point where the author says that in order to "feel" a sense of safety, we do not like paradoxes. I think that we pretend to ignore that paradoxes are an integral part of our lives, just that we ignore it hoping that it will go away.
But the more we accept that, the more security we will feel in the insecurities that these paradoxes present ;-)
