Vignana Bhairava Tantra - 70

Remembering the embrace

If Shiva were to be conducting a modern-day meditation workshop, then this verse would feature under the category of "Strictly for couples alone!" There is a direct allusion to sex and a glimps of ananda. When the man remembers totally the kissing, hugging and pressing embrace of a woman and the joy that arises out of sexual union, oh queen among gods, (Parvati), even at the time when the women is absent, the bliss that is present ever swells from within.
Being aware of this bliss totally you become aware of the witness who is watching the event of bliss arising out of the sexual experience.
Tantra shows the day-to-day path to meditation. And this is one way which makes use of the explosive energies involved in the sexual act to turn the mind inwards toward the awareness.

When Shiva and Shakti unite.....

In all of the Vignana Bhairava Tantra, it is this verse and the next that refer to the topic that Tantra is famously misunderstood and misquoted for. Shiva tells his wife Parvathy, yet another way of experiencing the truth.
At the time of union with shakti (woman) in a physical communion, there is an experience of excitement at the time of getting absorbed in the experience. That experience of pleasure when witnessed totally, you discover the Brahma Tatwa. Watching that experience dispassionately gives you a glimpse of the one who watches - the Brahman.
Tantra is unique in the sense that it does not deny any aspect of life by calling it bad or taboo. It includes every aspect of daily life, including sex and showing the means of realisation through all that we do. - Swahilya Shambhavi. (Tiruvannamalai hills from my view atop a building's terrace.)
