Whatsoever we call sex is just one dimension of life-energy. There are other dimensions. And really it should be so. You see a seed sprouting, somewhere flowers are coming on a tree, the birds are singing – the whole phenomenon is sexual. It is life manifesting itself in many ways. When the bird is singing it is a sexual call, an invitation. When the flower is attracting butterflies and bees it is an invitation, because the bees and butterflies will carry the seeds of reproduction. Stars are moving in space….

No one has yet worked on it but it is one of the oldest Tantra concepts that there are male planets and female planets – otherwise there would be no movement. It must be so because the polarity is needed, the opposite is needed to create magnetism, to create attraction. Planets must be male and female. Everything must be divided into these two polarities. And life is a rhythm between these two opposites. Repulsion and attraction, coming nearer and going far… these are the rhythms.
