I found a sermon that is very nice to read in the time of the COVID-19. It was given by a Japanese monk of Buddhism. I quote, "Look closely at what a green caterpillar does before winter comes. It is a tiny creature, which becomes a chrysalis and wisely prepares for the coming of a severe season. It changes itself and survives the most difficult time for it. Why not we humans do change ourselves for survival of the time of trial?" Quote ends. You often face difficult times in your life. They surely happen before your eyes. Sometimes, we are stunned at the difficulties in winter. And, we again begin walking ahead in spring. It is a wise sermon, I believe.
