The theory of Tantra yoga is that partners release the intense energy of Kundalini. This energy is coiled deep within our body and moves up through the chakra zones to awaken the mind and spirit, achieving enlightenment.
Tantric yoga is associated with sexuality because the energy has to build within the first and second chakras. The first chakra, known as Mulandhara, is located at the base of the spine, and represents our foundation and connection to the earth. The second chakra, Svadishthana, is housed within our genitals, and helps us connect to others through emotion and desire.
Tantra means "expansion." Through the practice of spiritual energy and sensuality, a yogi removes physical boundaries in order to reach a greater awareness or consciousness. You can perform Tantric yoga techniques with a lover, a sibling, a friend, or a child, because the true intent of Tantra is not the expectation of sex, but rather the sharing of souls to honor a higher level of being. When you dedicate your focus on another, you recognize the divine within that individual, and within yourself.
Is there a sexual component to Tantra? Yes, lovers can experience a completely different level of the practice if their intent is to explore their desire on a more emotional plane. The Kama Sutra was developed for this journey. However, it surprises many when they realize the Tantric yoga interaction they have with their partner has nothing to do with coitus or even foreplay. Nevertheless, the sharing of sexual energy between adults can be a wonderful benefit to the practice.
As with any yoga method, there are many philosophies. Here are some books you may find helpful in your quest to understand Tantric yoga techniques and theory:
There are a number of Tantric yoga techniques you can perform alone, with a partner, or simply as a moment of reconnection with another person. Again, keep in mind that while the true purpose of Tantra yoga is not for basal sex, some of these methods may have a sexual component to them.
