SB 3.31.36

Lord Brahma's being captivated by the charm of his daughter or Lord Siva's being captivated by the Mohini form of the Lord are specific instances by the great demigods like Brahma and Lord Siva to instruct us that even they are captivated by the beauty of women, and what to speak of a ordinary conditioned soul.

Therefore, it is advised for everyone that one should not freely mix even with one's daughter or with his mother or with his sister because the senses are so strong that when they become infatuated, even there is no consideration of daughter, mother or sister. The best thing is, therefore, to practice controlling the senses by bhakti-yoga and by being engaged in the service of Madana-mohana. Lord Krsna's name is Madana-mohana, who can subdue the Cupid, god of lust. Being engaged in the service of the Madana-mohana only, one can cut down the dictates of Madana or Cupid. Otherwise it will be failure.
