White Jambhala or Dragon Jambhala (or Dzambhala Gapee in Tibetan) is the compassionate manifestation of the Bodhisattva Chenrezig (Guan Yin). He can remove the suffering of poverty and sickness, purify non-virtuous karma and karmic obstacles, avert disaster and sickness, and evolve bodhicitta mind.
The Tibetan legend said that a revered high lama, Atisha, was walking alone when he found a man starving and near death. After looking around and unable to find food for the old man, he cut flesh from his own body and offered it to the starving man. But the man refused to eat the his flesh. Being depressed and not knowing how else to help the man nearing death, Lama Atisha sat down next to him. At that point there was a blinding bright white light and before Atisha appeared Chenrezig of Compassion. He told Lama Atisha that he was going to manifest himself as the God of Wealth, Jambhala, and assure that those in poverty would suffer no longer.
