Tantra. It comes from two sanskrit roots, ’tan’ and ’tra’.
’Tan’ means expansion, and ’tra’ means explosion. Tantra means explosion by expanding your consciousness. In the new hippie jargon they have a word which means exactly tantra – mindblowing; that is what tantra is. And when you start expanding your consciousness it cannot be contained in the head. The head is a very small place, very crowded, already too crowded.
A thousand thoughts and desires are clamouring, it is a marketplace. Even while you are asleep it goes on functioning, it goes on chattering. When you start expanding then naturally you have to find a bigger place for yourself, and that is the heart. Then you start slipping from the head into the heart. The heart has great possibilities. It is an infinity. So start slowly, slowly, relaxing into the heart… dance and sing. And this is your family…
