Tibetans love to pray and recite mantras, and the Green Tara mantra is one of the main three or four matras that is said to help oneself and others. The first Dalai Lama wrote that we can call on her to instantly save us from eight particular dangers, each of which represents a corresponding human mental problem:
lions - pride
wild elephants-delusion and ignorance
robbers-wrong views, including fanatical views
prisons-greed and miserliness
floods-desire and attachment
demons - doubts caused by delusion
Ordinary Tibetans pray to her when they are sick, when leaving for a long journey or when they hope for success or wealth. When they chant the Green Tara mantra, they are not simply asking for Tara's blessings and help with their lives and their real world problems. They are also asking to be liberated from the misery of the mental delusions and negative emotions that blind them to true freedom and to achieve the same enlightened body, speech and mind that Tara represents, not only for their own benefit, but for the benefit of all sentient beings.
