While in a deep embrace with your beloved you can forget the other. Only then do you forget the other. A man forgets that woman exists; a woman forgets that man exists. Only in a deep embrace the other is no more, and when the other is no more your energy can flow easily.
Tantra says no strain is needed; be relaxed with the other. In that relaxed moment the other disappears and your energy can flow up, but it flows up only when you are in a valley. It flows down when you are at a peak.
