Are we of the world?

There was once a Hindu queen, who so much desired that all her children should attain freedom in this life that she herself took all the care of them; and as she rocked them to sleep, she sang always the one song to them — "Tat tvam asi, Tat tvam asi" ("That thou art, That thou art"). Three of them became Sannyasins, but the fourth was taken away to be brought up elsewhere to become a king. As he was leaving home, the mother gave him a piece of paper which he was to read when he grew to manhood. On that piece of paper was written, "God alone is true. All else is false. The soul never kills or is killed. Live alone or in the company of holy ones." When the young prince read this, he too at once renounced the world and became a Sannyasin.
