Tantra has an attitude about sex. The reason? — it tries to redress what the society has done. Tantra is medical. The society has repressed sex; Tantra comes as a remedy to help you redress balance. You have leaned too much to the left; Tantra comes and helps you to lean to the right. And to redress the balance sometimes you have to lean too much to the right, only then the balance is gained. Have you not seen a rope walker, a tightrope walker? He carries a staff in his hand to keep balance. If he feels he is leaning too much to the left, he immediately starts leaning to the right. Then again he feels that now he has leaned too much to the right, he starts leaning towards the left. This is how he keeps in the middle. Tantra is a remedy.
