A teaching from 2016 - Gratitude cures 90% of spiritual ills but being ungrateful causes some problems. "I hate ingratitude more in a man than lying, vainness, babbling drunkenness, or any taint of vice whose strong corruption inhabits our frail blood...Ingratitude is monstrous; and for the multitude to be ungrateful, were to make a monster of the multitude." - William Shakespeare.
