Two Enemies of human life
According to the Shastras [ancient books of wisdom] the two main enemies of human life are supposed to be ignorance and laziness. Because through ignorance we avoid the good; through ignorance of consequences we accept the evil. Through laziness we are not able to change ourselves.
