Pondering excessively on the suffering of others seems to cloud my perspective...
In the medical setting, it behooves one to reflect on the existence of pain/suffering because it helps one empathize with patients, presumably enhancing the doctor-patient relationship. Looking at someone in the eyes with intent and expressing sympathy can open a channel of understanding and rapport. Still, no degree of empathy can amend the harsh reality: sick people suffer. As any good Samaritan, you strive to alleviate the experience of suffering-- sometimes to no avail, like standing idle before a burning at the stake.
So as [any] coward, I avoid thinking about its metaphysical origin-- I still cannot find a good reason for its existence. Considering all the meaningless reasons for the suffering of people, why should one bother to rationalize or make sense of them?
There is a box inside of me where at the end of the day, I place all these moments. I make an effort each day to close the box before returning home. As usual, the very next day this sealed box cracks open. If fortune smiles, each will say "...0/10 today.”
