Ref : Mahabharatha, Santhiparva
"Vyasa said, 'The words of Arjuna, O amiable Yudhishthira, are true. The highest religion, as declared by the scriptures, depends on the duties of domesticity. Thou art acquainted with all duties. Do thou then duly practise the duties prescribed for thee (viz., the duties of domesticity). A life of retirement in the woods, casting off the duties of domesticity, has not been laid down for thee. The gods, Pitrus, guests, and servants, all depend (for their sustenance) upon the person leading a life of domesticity. Do thou then support all these, O lord of the earth! Birds and animals and various other creatures, O ruler of men, are supported by men leading domestic lives. He, therefore, that belongs to that mode of life is superior (to all others). A life of domesticity is the most difficult of all the four modes of life. Do thou practice that mode of life then, O Partha, which is difficult of being practiced by persons of unrestrained sense."
