Tantra, being a development of Atharva Vedic and pre-Brahmanical thought, embraced the Hindu gods and goddesses, especially Shiva and Shakti, along the Advaita (nondualist Vedic) philosophy that each represents an aspect of the ultimate Param Shiva, or Brahman. These deities may be worshipped externally (with flowers, incense etc.) but, more importantly, are used as objects of meditation, where the practitioner imagines him - or herself to be the deity in question. The ancient devadasi tradition of sacred temple-dance, seen in the contemporary Bharata Natyam is the example of such meditation in movement. The divine love is expressed in Sringara and Bhakti.
