Avalokiteshvara, or Chenresig in Tibetan, is an enlightened being who is a manifestation of all Buddhas' compassion. He is known as the Buddha of Compassion and is usually depicted as white in color with four arms. His first two hands are pressed together at his heart, symbolizing his respect for his Spiritual Guide, Buddha Amitabha, who is on his crown.
The first two hands also hold a jewel, which symbolizes his own enlightenment. This mudra is indicating that he attained a jewel-like great enlightenment through receiving blessings from his Spiritual Guide Amitabha.
His second left hand holds a white lotus flower, which symbolizes that because he attained enlightenment he is free from all obstacles and has a completely pure body, speech and mind. His second right hand holds a crystal mala, symbolizing that he can free all living beings from samsara and lead them to liberation.
Buddhist Stupas, Temples, and crafts often feature statues, sculptures, and metal décor of Tibetan style from copper, brass, and gold finishing as per Buddhism bodhisattva blessings.
If we rely sincerely upon Avalokiteshwara and recite his mantra with strong faith, we can temporarily improve our realizations of the stages of the path, especially our realization of great compassion, and ultimately attain supreme Buddhahood in Avalokiteswara's Pure Land, the Pure Land of Bliss.
