Tantra arose in the second century in India and Tibet. It is rooted in the esoteric tradition of Hinduism and Buddhism. Tantra is not a religion, but a certain kind of philosophy that includes all aspects of life.
Tantra means “weaving; expanding”
Tantra teaches that all beings are connected with the utmost love and wisdom.
The tantric practices open our heart, calm our soul and let us feel our vital energies.
Shiva and Shakti are seen as equal representatives of the highest supreme divinities, they are alive inside us as the masculine (Shiva) and feminine (Shakti) principles. Shiva means consciousness and Shakti means energy. When Shiva and Shakti build a union, there is a state of cosmic consciousness.
During the Tantra massage we can achieve access to another state of consciousness, the system of the body`s energy is being realigned and self-healing powers are being activated. There is an enhancement of inner development and growth.
