Tantra first teaches how to move in sex, how to know it, how to feel it, how to come to the deepest shiva cosmic dance possibility hidden in it, to the climax, how to find the essential beauty, the essential happiness and bliss that is hidden there.
Once you know that secret you can transcend it because, really, in a deep sexual orgasm it is not sex which gives you …bliss, it is something else. Sex is just a situation. Something else is giving you the euphoria, the ecstasy. That something else can be divided into three elements. But when I speak about those elements, do not think that you can understand them just from my words. They must become part of your experience. As concepts they are useless. Because of three basic elements in sex you come to a blissful moment.Those three are:
You transcend time completely. There is no time. You forget time completely; time ceases for you. Not that time ceases, it ceases for YOU; you are not in it. There is no past, no future. In this very moment, here and now, the whole existence is concentrated. This moment becomes the only real moment. If you can make this moment the only real moment without sex, then there is no need of sex. Through meditation it happens.
~Secondly, You Become Egoless
In sex for the first time you lose your ego. So all those who are very much egoistic, they are all always against sex, because in sex they have to lose their egos. You are not, nor is there the other. You and your beloved are both lost into something else. A new reality evolves, a new unit comes into existence in which the old two are lost – completely lost. The ego is afraid. You are no more there. If without sex you can come to a moment when you are not, then there is no need of it.
~Thirdly, the Unreal is Lost
In sex you are natural for the first time. The unreal is lost, the faces, the facades are lost; the society, the culture, the civilization, is lost. You are a part of nature. As trees are, as animals are, as stars are, you are a part of nature. You are in a greater something – the cosmos, the Tao. You are floating in it. You cannot even swim in it; YOU are not. You are just floating – being taken by the current.
These Three Things Give You the Ecstasy
Sex is just a situation in which it happens naturally. Once you know and once you can feel these elements, you can create these elements independently of sex. All meditation is essentially the experience of sex without sex, but you have to go through it. It must become part of your experience, not just be there as concepts, ideas, thoughts.
Tantra is not for sex, tantra is to transcend. But you can transcend only through experience – existential experience – not through ideology. Only through tantra does Brahmacharya happen. This looks paradoxical, but it is not. Only through knowledge does transcendence happen. Ignorance cannot help you towards transcendence; it can only help you towards hypocrisy.
