the thousand arms of guanyin

As seen on Break.com

mahayana buddhists of northern india, nepal and tibet had long been depicting the bodhisattva avalokiteshvara with a thousand arms - to show that he has his helping hands everywhere for everybody. when buddhism came to china, the chinese made a female goddess out of the male bodhisattva, possibly because the qualities of being merciful and having one's eyes and hands everywhere were associated with a mother rather than a young man - still, they painted and sculpted her with a thousand arms, sometimes with an eye in the palm of each hand.
over the times, a dance developed, where a row of dancers, one behind the other, pretend that they are one goddess with many arms. (this, too, may have been inspired by indian tradition, since in classical indian dance sometimes four dancers represent an eight-armed shiva in the same way.)

the chinese name of the feminized bodhisattva is guanyin - or, in its full form guanshiyin "the one who listens to the sounds of the world". the dancing girls in the video do not listen to any sounds, not even to the music. they can't, because they are deaf... and they belong to the Disabled People Performing Arts Troupe of china.
