This is a gorgeous Buddha Chitta or Bodhi Chitta or Bodhichitta prayer mala from Nepal. Bodhi is a Sanskrit word which means "enlightenment" and ‘chitta’ the word for ‘mind' therefore ‘bodhichitta’ supreme happiness.
This Bodhi Chitta is used for chant, prayer, meditation, yoga. The mala is very well made and is in good condition.
