A stumbling point for me in the practice of Buddhism is optimism. I do not do optimism. My thoughts on optimism parallel Ambrose Bierce.
Optimism: The doctrine that everything is beautiful, including what is ugly, everything good, especially the bad, and everything right that is wrong… It is hereditary, but fortunately not contagious.
I am particularly prone to pessimism (realism) when it comes to the response of our species to climate change. In reading the parable of the Burning House from the Lotus Sutra, I am tempted to wonder (which is as close as I come to hope).
