Another legend has it that once, many eons ago during the time of Buddha Dundubhisvara, there lived a princess by the name of "Moon of Wisdom-knowledge" or "Moon of Knowledge" (Jnanacandra). She was a very devoted disciple, and would daily set out many precious and costly offerings to the Buddha and his sangha. Eventually, she aspired to attain full enlightenment, in order to benefit all living beings.


Princess Moon of Knowledge eventually attained a meditative power called "Saving All Beings." Every morning before breakfast she helped to liberate millions of beings, and she repeated the feat each evening. Therefore, she became known as Tara, "Savioress." In the following aeon, Tara vowed to protect all beings in the universe from harm.
