This beautiful statue of Vajrasattva  is made by the artisans of Nepal. It is made of brass.
 
Vajrasattva carries a vajra (thunderbolt) in his right hand which destroys all kinds of ignorance and is indestructible and a ghanta (bell) in the left which symbolizes the feminine principle. In tantric rituals, their interaction leads to enlightenment.
Vajrasattva is locked in a close embrace (yab-yum) with his Shakti. His Shakti holds a kartri (curved knife) in her right hand which symbolizes separation from all material possessions and a kapala (cut of the skull) in her left.
 
Yab-Yum (Tibetan) is a tantric symbol of the mystical union of masculine and feminine polarities. The masculine energy is compassion and the feminine energy is wisdom. The two acting in concert form the enlightened mind.
 
Signification:
Purifying karma, accomplishing broken samayas (times)
