That is the meaning of this Japanese phrase. It reminds me of the scripture in the New Testament, John 14:27. Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
If you will see, or ears to hear and comprehend, I will explain. I have made a covenant to remember and obey the Savior. I have chosen throughout my life to obey the commandments. Teachings of an inspired law of health have guided me to not ingest substances that are bad for my health, particularly my respiratory system. I have also tried to obey the positive counsel about eating wisely. Using vegetables and grains as the primary source of my diet. Exercising and watching my weight to keep my body and mind strong. I have made sacred promises, called covenants, with my wife, to live my life so that I can have the companionship of the Spirit of God with me....
That is why my heart is neither troubled nor afraid at this time and being about working among the public does not bother me. And if I contracted the virus, and died tomorrow, I would have no regrets about the life I have lived.
