"Today is so good" is a state of mind that is "indifferent and clear-minded, peaceful and far-reaching". In this state of mind, we will truly examine ourselves and face life, we will not complain about life, we will not bow our noble heads to life, we will surpass our own limits in life, and we will always be confident in life. Maybe we are more miserable today than yesterday, but isn’t pain the medicine God gives us to heal our wounds?
