TRANSLATION
To render service to the husband, to be always favorably disposed toward the husband, to be equally well disposed toward the husband's relatives and friends, and to follow the vows of the husband — these are the four principles to be followed by women described as chaste.
PURPORT
It is very important for peaceful householder life that a woman follow the vow of her husband. Any disagreement with the husband's vow will disrupt family life. In this regard, Canakya Pandita gives a very valuable instruction: dampatyoh kalaho nasti tatra srih svayam agatah. When there are no fights between husband and wife, the goddess of fortune automatically comes to the home. A woman's education should be conducted along the lines indicated in this verse. The basic principle for a chaste woman is to be always favorably disposed toward her husband. In Bhagavad-gita (1.40) it is said, strisu dustasu varsneya jayate varna-sankarah: if the women are polluted, there will be varna-sankara population. In modern terms, the varna-sankara are the hippies, who do not follow any regulative injunctions.
Another explanation is that when the population is varna-sankara, no one can know who is on what platform. The varnasrama system scientifically divides society into four varnas and four asramas, but in varna-sankara society there are no such distinctions, and no one can know who is who. In such a society, no one can distinguish between a brahmana, a ksatriya, a vaisya and a sudra. For peace and happiness in the material world, the varnasrama institution must be introduced. The symptoms of one's activities must be defined, and one must be educated accordingly. Then spiritual advancement will automatically be possible.
