How to see
To avoid the sin of lustful desire, a man should see women as sisters, or daughters, or mothers, loving whom would be incest. He can also see woman as his own self, falling in love with whom would be narcissism.
Yet this is dishonesty. You must learn to see women as women, and men as men. Have nothing to do with what is merely the skillful use of the imagination and trickery. The opposite sex are literally a part of your own Infinite body. Seeing the Infinite, and being the Infinite, how can you ever distinguish any such thing as "family", or feel any kind of feeling towards others - you who know nothing other than the Love of God. If you are honest you will be hated, for there is nothing people hate more than Infinite Love: it is an opposite of what they call love.
If you are a man, then never let a woman catch you looking at her; for how can you teach her non-attachment when you are attached to physical and emotional beauty yourself? And don't think you can get away with picturing beautiful women in your mind, for where the mind wanders the eyes will follow.
