thousand armed avalokitesvara

One prominent Buddhist story tells of Avalokiteśvara vowing never to rest until he had freed all sentient beings from saṃsāra. Despite strenuous effort, he realizes that many unhappy beings were yet to be saved. After struggling to comprehend the needs of so many, his head splits into eleven pieces. Amitābha, seeing his plight, gives him eleven heads with which to hear the cries of the suffering. Upon hearing these cries and comprehending them, Avalokiteśvara tries to reach out to all those who needed aid, but found that his two arms shattered into pieces. Once more, Amitābha comes to his aid and invests him with a thousand arms with which to aid the suffering multitudes.
