Revisiting Max Ehrmann’s Desiderata, I am reminded of the wisdom of this passage:
“Nurture strength of spirit to shield you in sudden misfortune. But do not distress yourself with imaginings. Many fears are born of fatigue and loneliness. Beyond a wholesome discipline, be gentle with yourself.”
There is such a “yin and yang” in this. Toughen yourself to deal with misfortune, but don’t worry too much. Be disciplined , but be gentle with yourself.
It occurs to me that this is classic “in the world but not of the world” thinking which, as most things seemingly do, leads me back to Paul and Romans 12:2 – “do not confirm any longer to the pattern of this world, but be transformed by the renewing of your mind.”
