The combination should be that the husband should be first-class devotee, Krsna conscious, and woman should be, woman should be devoted to the husband, faithful, so that she would help the husband to make progress in Krsna consciousness. Then their both life is successful. Otherwise, if the husband simply becomes captivated by the charming beauty of woman and engages himself in the sex life, then his life is lost, and the woman, they are less intelligent, unless they are guided by proper husband, her life is also lost. So those who are not demigods… Here it is said, apayayat suran. Sura-asura. Sura, those who are not developed to Krsna consciousness, they are asura. So every husband should be a sura. Sura means devotee. And every woman should be religious. Religious means to become chaste, faithful to the husband. And the husband should become a devotee. Then both of them will make progress in Krsna consciousness and that is the perfection of life.
