A householder may have wife, may have sex life, but that is for having children only, that’s all. A householder does not mean he gets license to legalize prostitution. That is not householder. Householder can simply have sex life to beget nice child, that’s all, no more. That is householder life; completely controlled. Householder does not mean whenever he has got this machine and he can use it. No.
