Tara is the mother of compassion, the female aspect of Buddha, inseparable from the enlightened awakened state.
According to the various lineages of Tibetan Buddhism, the list of Tara names can vary.
Of the 108 names and 21 forms and numerous colors of Tara, two are most popular:
White Tara, Sanskrit Sitatāra, identified with the Princess of China, wife of the first Buddhist king of Tibet.
Green Tara, Sanskrit Syamatāra, identified with the Princess of Nepal, second wife of this same king.
Red Tara, Rigdjed Lamo in Tibetan, which evokes our natural awakened state, called rigpa.
The cult of Tara in Tibet spreads under the influence of the ardent Indian devotee Atisha,Sanskrit Atiśa, who arrived in the country in 1042.
The 21 forms of Tara correspond to the Indian liturgical text "Homage to the 21 Taras", brought to Tibet by Dharmadra, also in the 11th century and relate to specific functions and characteristics and associated with propitiatory gestures, or mudras and sacred syllables, or mantras.
