Definition of Tantra:
Tantra or tantrism is a traditional technique to focus the body on a specific discipline.
Tantra is one of the trends in contemporary Hinduism and is the main practice in all schools of Tibetan Buddhism.
In Hinduism there are two Tantras: the right hand path and the left hand path. The latter includes meditation and ritualization techniques through the sexual act through which the feminine and masculine energies are integrated.
In Hinduism, they are often couched as a dialogue in which the god Shiva answers questions from his wife Devi in the roles of teacher and disciple.
