Today, in the Western collective imagination, Tantra mainly refers to sexuality. In reality, in the Vijnana Bhairava Tantra, a founding Sanskrit text from cashmere and dating from the 8th century AD, there are only 3 stanzas out of 112 that concern sexuality. Tantra of Indo-Tibetan origin is therefore much larger than that.
It is a practice of awakening by becoming aware of the feeling: a path of experience, a direct path, a non-dual path.
The experience of non-duality is the experience between the individual and the absolute, an experience of being, of pure joy, of deep tranquility. When we are in duality, we live ourselves as a subject, away from objects: me and the rest of the world, there is separation between me and the world. When one experiences non-duality, moments of grace, moments of awakening, the separation disappears and the world is in itself. Most of us have already experienced it.
In front of a beautiful landscape, you can have the feeling of becoming one with the landscape.
Listening to music, one can become pure listening.In love and sexuality, one can feel fully connected and become pure sensation.
The limits of the body are no longer perceptible, everything is unified, without separation. The world becomes sensory.
This non-dual tantric approach, also called direct path, points to our true nature. It does not lead to freedom but allows us to see what prevents liberation.
The non-dual orientation offers to see the extent of our resistance, of our bodily reactions. It is also called negative way because it results from the elimination of what we are not.
It is through the work of the body, listening to the feelings, that prejudices are challenged and that we become aware of reality as it is and not as we would like it to be.
