According to the bodily demands, there are sexual necessities. Women should not only give sex pleasure to their husbands, but should also prepare good food. After coming home from a day of hard work, the man should be supplied good food, comfort, and sex. Then the home becomes very happy, and both husband and wife are satisfied.
Then they can improve their real business, which is spiritual understanding. Human life is meant for progressing spiritually, and people must first of all know that the spirit soul is at the basis even of material life. The body is built upon the soul. Although women are generally less intelligent, this understanding is required of both men and women. With the help of the husband, a woman can become more intelligent. In Vedic history, we have the example of Kapila-deva giving spiritual instructions to his mother Devahuti. Whether the woman is a daughter, wife, or mother, if she remains subordinate, she can receive knowledge from either her father, husband, or son. In the Puranas, there is the example of Lord Siva answering the spiritual questions of Parvati. Women supply the comforts of the tongue, belly, and genitals, and, remaining submissive, they are instructed in spiritual life. Thus there is cooperative advancement.
