principle makes its first appearance in Buddhism as the goddess who personified prajnaparamita. Tārā came to be seen as an expression of the compassion of perfected wisdom only later, with her earliest textual reference being the Mañjuśrī-mūla-kalpa (c. 5th–8th centuries CE). The earliest, solidly identifiable image of Tārā is most likely that which is still found today at cave 6 within the rock-cut Buddhist monastic complex of the Ellora Caves in Maharashtra (c. 7th century CE), with her worship being well established by the onset of the Pala Empire in Eastern India (8th century CE). Tārā became a very popular Vajrayana deity with the rise of Tantra in 8th-century Pala and, with the movement of Indian Buddhism into Tibet through Padmasambhava, the worship and practices of Tārā became incorporated into Tibetan Buddhism as well.

She embodies the motivation that is compassion and is said to be as white and radiant as the moon. Origin as a Buddhist bodhisattva Tārā has many stories told which explain her origin as a bodhisattva. In this tale there is a young princess who lives in a different world system, millions of years in the past. Her name is Jnanachandra or Yeshe Dawa, which means "Moon of Primordial Awareness". For quite a number of aeons she makes
