Greed

O King! 

1. This greed is the greatest enemy of a man, residing in his own body; 
2. this greed is the root of all evils, of all sins. Life is in danger due to this covetousness. 
3. It is due to this greed that quarrels ensue amongst the several castes, the Brâhmins, etc., and that the human beings are very much troubled with thirst after worldly enjoyments. 
4. This greed makes a man forsake all his religious rites and long existing customs and observances of his family; and it is due to this avarice of gold that men kill their fathers, mothers, brothers, friends, Gurus, sons, acquaintances, sisters, and sisters-in-law and others. Really when a man is bent on avarice, nothing heinous remains to him that cannot be done by him. 
5. This greed is a more powerful enemy than anger, lust and egoism.
