As the tortoise tucks its feet and head inside the shell and will not come out even though you may break the shell into pieces, even so the character of the man who has control over his motives and organs, is unchangeably established . He controls his own inner forces, and nothing can draw them out against his will. By this continuous reflex of good thoughts and good impressions moving over the surface of the mind, the tendency to do good becomes strong , and in consequence we are able to control the Indriyas or sense organs.
Which of the following statements would be most correct in explaining the metaphorical meaning of break the shell into pieces ?

Options

A. Destruction of the human body
B. Breaking of the physical environment of man
C. Attempt to destroy man's character
D. Inflicting physical and mental agony on man
