Grhastha means to live with wife and children, and cultivating spiritual life. That is called grhastha. It doesn't matter, you live with your wife and children, or you live with brahmacari, sannyasi. Anything. It doesn't matter. Therefore there are so many divisions of life. Whichever status of life is suitable for you, you can accept. Brahmacari, grhastha, vanaprastha, sannyasa asrama. Asrama, when the word is added, asrama, that means it has got reference with cultivation of spiritual life. So grhastha-asrama. One can live at home with wife and children, but the business should be Krsna consciousness. We don't accept the Mayavadi sannyasi because there is no Krsna consciousness.
