"だるま DARUMA" is a hollow, round, Japanese traditional amulet, tumbler doll modeled after 'Bodhidharma', the founder of Zen sect of Buddhism. Bodhidharma was a Buddhist monk who lived during 5th/6th century AD.
Legend claims that he sat facing a wall in meditation for a period of nine years without moving, which caused his legs to fall off from atrophy. Therefore Daruma doll doesn't have legs.
Nowadays "Daruma" is regarded more as a bringer of good luck. Daruma doll is weighted on the bottom, so it always recovers upright position whenever it is swinging. As such, It is a symbol of revival and "never giving up" to reaching the objective, as it always stands up positively.
Initially, the doll has eyes without pupils. Oversized symmetrical round blank white eyes mean to keep track of goals or big tasks and motivate them to work of the finish. The owner of the doll fills in the left eye of the Daruma, upon setting the goal and makes a wish. And at later stage, add the right eye when and if the wish comes true.
