daruma
A hollow, round, Japanese traditional doll modeled after Bodhidharma, the founder of the Zen sect of Buddhism.
Like a daruma doll, you knock it over and it rights itself.
Where it comes from
Borrowed from Japanese 達磨 (daruma), from Sanskrit धर्म (dhárma, “law; morality; code”), used as a clipping of 菩提達磨 (Bodaidaruma, “Bodhidharma”). Doublet of Dharma.
