It is to this law that our souls must adjust themselves, this they should follow, this they should obey. Whatever happens, assume that it was bound to happen, and do not be willing to rail at Nature. That which you cannot reform, it is best to endure, and to attend uncomplainingly upon the God under whose guidance everything progresses; for it is a bad soldier who grumbles when following his commander.
Without accepting the fact that everything changes, we cannot find perfect composure.
To every thing there is a season, and a time to every purpose under the heaven: A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted; A time to kill, and a time to heal; a time to break down, and a time to build up; A time to weep, and a time to laugh; a time to mourn, and a time to dance.
