Gatha vyatah means that there should be no worry regarding what is past. A man with worries can never accomplish anything. One should not worry about what is past or what is in the womb of the future. It is such worry that is the cause of all of man’s troubles. There is no meaning in worrying about the unknown future. Keeping the present in view, men should engage themselves in right actions. The past and the future are in the present. Devotees who do their duty in the present are dear to the Lord. (D3 , p. 358)
