Sanskrit:  शमदमाद्युपेतः स्यात्तथाऽपि तु तद्विधेस्तदङ्गतयातेषामवश्यानुष्ठेयत्वात्  .  
English:  (Even though there be no injunction about sacrifices etc.,), still one must be endowed with self-control and the like, since these are enjoined as subsidiaries of knowledge; and hence have to be practised as a matter of course.
