The 21 Taras are the Mother of all the Buddhas and White Tara lengthens their lives so they can do more good while they are here in physical form

If you would help to lengthen your life one way besides Diet and Clear Right minded thinking and exercise is to get a White Tara Initiation and to do a Long Life White Tara Practice from a Tibetan Lama you have a connection with and that you trust.

Right minded thinking simply means to be compassionate in a pragmatic Way that helps the most beings possible end their suffering and enter an eternity of Bliss and happiness.

25% of all Buddhists believe in God and so I am one of these that are both mystical Christian and Tibetan Buddhist as well.

There is no conflict between Christianity and Buddhism at all because Christians don't consider Buddhism a religion but rather a philosophy so they practice Buddhism like Hatha Yoga so many ministers and priests who are Christian are also Buddhists learning to have compassion for all life in the physical universe and beyond.

begin partial quote from previous article:

White Color: Stands for the pure truth of the Dharma and untainted wisdom.
Seven Eyes: Depicted with eyes on her face, palms, and soles of her feet, symbolizing her watchful, all-seeing compassion for suffering beings across the universe.
The Trio of Longevity: She is frequently grouped alongside Amitayus and Ushnishavijaya as the core triad of long-life practices. 
end quote.
If you look at the poster in one of the last articles you can see for yourself the eyes on the forehead and in the palms of her hands and in the souls of her feet visibly in the poster. This means full awareness in all directions into the past, present and future like Christian Angels too who also live in the past, present and future throughout the spiritual and physical universe.
