All empty souls tend to extreme opinion. It is only in those who have built up a rich world of memories and habits of thought that extreme opinions affront the sense of probability. Propositions, for instance, which set all the truth upon one side can only enter rich minds to dislocate and strain, if they can enter at all, and sooner or later the mind expels them by instinct.
The Bhagavad-Gita calls on humanity to dedicate body, mind and soul to pure duty and not to become mental voluptuaries at the mercy of random desires and undisciplined impulses.
