Te sadhu-krta-sarvartha. Artha means interest. Everyone has some interest. The animals have got also interest. The man has got some interest. The big politician, he has also interest. Everyone has got interest. But nobody knows what is real interest. That is missing. Everyone has created his interest and he is working in that way. Na te viduh svartha-gatim hi visnum [SB 7.5.31]. Real interest is, for the human being, to know what is God, what is my relationship with Him, and how I shall achieve the highest perfection of life. That is real interest.
