Courage is not an obscure word yet I would like to share a definition here: Mental or moral strength to venture, persevere, and withstand danger, fear, or difficulty.
Webster Dictionary
I am not sure how you feel after reading that or what it brings to your mind, but to me it describes very accurately how we practice the Lotus Sutra. We practice with courage. Daily we challenge both our mental and moral strength to carry out a very difficult practice, sometimes in environments that are less than supportive. Practicing the Lotus Sutra requires of us to persevere even in the face of sometimes seemingly insurmountable obstacles.
