The tempting self and unquenchable desires

"The tempting self and unquenchable desires are the great enemies of a human being because they are the enemy of one’s intellect. The Prophet (S) regards the tempting self and its desires as enemies because “the real friend of everyone is his intellect.” We can defend our self against every enemy using the power of intellect; however, if an enemy is able to steal one’s intellect, it would be most dangerous."
