Tara and female energy

Tara embodies many of the qualities of feminine principle. 

Introduction.

Tara embodies certain ideals which make her attractive to women practitioners. According to  H.H. the Dalai Lama about Tara,  at a conference on Compassionate Action in Newport Beach, CA in 1989:

"There is a true feminist movement in Buddhism that relates to the goddess Tārā. Following her cultivation of bodhicitta, the bodhisattva's motivation, she looked upon the situation of those striving towards full awakening and she felt that there were too few people who attained Buddhahood as women. So she vowed:

"I have developed Bodhicitta as a woman. 

For all my lifetimes along the path I vow to be born as a woman, 

and in my final lifetime when I attain Buddhahood, then, too, I will be a woman."

Mother of Mercy and Compassion. 

She is the source, the female aspect of the universe, which gives birth to warmth, compassion and relief from bad karma as experienced by ordinary beings in cyclic existence. 
She engenders, nourishes, smiles at the vitality of creation, and has sympathy for all beings as a mother does for her children.

The Female Qualities of Tara

Within Tibetan Buddhism, Tara (Mother of all Buddhas) has 21 major forms in all, each tied to a certain colour and energy. And each offers some feminine attribute, of ultimate benefit to the spiritual aspirant who asks for her assistance.

Another quality of feminine principle which she shares with the dakinis is playfulness. Applied to Tara one could say that her playful mind can relieve ordinary minds which become rigidly serious or tightly gripped by dualistic distinctions.

She takes delight in an open mind and a receptive heart. 

For in this openness and receptivity her blessings can naturally unfold and her energies can quicken the aspirants spiritual development.

Mother of Perpetual Help

When we need help in a hurry, Tara is the “swift one”:

If in trouble, Green Tara. 
If sick, White Tara (Sita Tara).

In Tibet, there’s a saying, “For protection, call on your protector if you have time—but call on Tara if you have no time.”

Mantras were given by the Buddhas via Sutra or transmission of lineage, and carry great cumulative, power. Mantra literally can translate as “mind protection.” 

Since mind affects health, a Sanskrit mantra dedicated specifically to healing is very effective.

Tara's Mantra

The meaning of the root mantra of Tara (Om Tara Tuttare Ture Soha) is explained numerous ways by many great teachers, all of which are complimentary and correct. 

Lama Zopa Rinpoche taught:

“TARE shows that Mother Tara liberates living beings from samsara”

“TUTTARE liberates you from the eight fears related to the external dangers from fire, water, air, earth and also from such things as thieves and dangerous animals. However the main dangers come from ignorance, attachment, anger, pride, jealousy, miserliness, doubt and wrong views.”

“TURE liberates you from disease”

so Green Tara is equally the Healer as White.
