Red Tara is one Buddhist Dakini originating from the country of Uddiyana is the goddess Kurukulla. The name Kurukulla is translated into Tibetan as Rigjyedma (rig-byed-ma), “she who is the cause knowledge.”
She is associated with a king of Uddiyana named Indrabhuti. But there were at least three Indrabhutis and this is most likely the second one.
Moreover, there exists a sadhana text attributed to him for the red Kurukulla in her eight-armed form. But whether she had eight arms or four arms, she is generally known as the Uddiyana Kurukulla.
Most modern scholars believe this indicates that Kurukulla was originally a tribal goddess, much like the Hindu goddess Durga had been in India, who later, because of her popularity, became associated with the Buddhist great goddess Tara.
For this reason, Kurukulla is often called the Red Tara (sgrol-ma dmar-po) or Tarodbhava Kurukulla, “the Kurukulla who arises from Tara.”
