The body is a beautiful vehicle - very mysterious, very complex. Use it, do not fight with it. Help it. The moment you go against it you are going against yourself. It is as if a man wants to reach somewhere, but he fights with his own legs and cuts them. Tantra says, know the body and know the secrets of it. Know the energies of it and know how those energies can be transformed - how they can be moved and turned into different dimensions.
Tantra has no condemnations, only secret techniques for how to transform. That is why tantra talks so much about the body - it is needed. The body has to be understood, and you can start only from where you are.
