The Vajra Bolt is the symbol of Dharmanatha, the fifteenth Jain Tirthankara of the present age. Dharmanath was born in Ratnapuri to King Bhanu Raja and Queen Suvrata Rani during the Ikshvaku dynasty. His birthday fell on the third day of the Indian calendar's Magh Sukla month. According to Jain teachings, he became a Siddha, a purified soul who has destroyed all of its karma. Dharmanatha is associated with Vajra.
