Tantra has been one of the most neglected branches of Indian spiritual studies despite the considerable number of texts devoted to this practice, which dates back to the 5th-9th century AD.
Many people still consider tantra to be full of obscenities and unfit for people of good taste. It is also often accused of being a kind of black magic. However, in reality, tantra is one of the most important Indian traditions, representing the practical aspect of the Vedic tradition.
The religious attitude of the tantriks is fundamentally the same as that of the Vedic followers. It is believed that the tantra tradition is a part of the main Vedic tree. The more vigorous aspects of Vedic religion were continued and developed in the tantras. Generally tantriks worship either Goddess Shakti or Lord Shiva.
