This too much intermingling of woman means the path of hell. Therefore the restriction is that only the married couple can freely mix, not others. Mahat-sevam dvar… That is the defect of the modern civilization. They are not interested associating with devotees. They are interested associating with man or woman, that's all. Woman is interested to associate with man, and man is interested to associate with woman. Yositam sangi-sangam [SB 5.5.2]. Therefore the civilization is becoming hellish. It is already said in the sastra. One should associate with spiritually advanced men, but that is not being done. Now the woman is hankering after man, man is hankering after woman. Yosit sang… Yosit means for sense gratification. Tamo-dvaram. This is the path of darkness.
