Tantra doesn’t exclude hedonism, but neither does it encourage it. It is very much the ‘middle way’ that characterises all Buddhist vehicles.
Tantra is not concerned with seeking extremes – even though extreme sensation can be cultivated as a powerful aspect of the path. Fundamentally, Tantra neither seeks extremity nor avoids it. The intrinsic power of any sensation becomes manifest through our realisation of its empty nature.
