Just like I have several times said, the marriage is sense gratification, sex life. But somebody may say... They say that "Marriage is legalized prostitution." It may be, but still, there is some control. Although it is called "legalized prostitution," there is no difference between prostitution and married life, but there is some control. People become responsible. By responsible life, they can make advance. Irresponsible life will not help. Therefore loke vyavāyāmiṣa-madya-sevā nityā hi jantoḥ. So our tendency for sense gratification is controlled. Therefore it is called license. Gṛhastha life means a license for sense gratification. But we must know that sense gratification means material life. It may be systematic or not systematic. Sense gratifications means material life. But our aim is to transcend this material life and come to the spiritual life, platform of spiritual life. That is required. So there are so many processes.
