Tibetan Dorje (Vishwo Vajra) represents the indestructibility and efficiency that overcomes all obstacles. Symbolically, Dorje Vajra destroys ignorance. In Tibetan Buddhist rituals, the vajra is often used with the bell, representing the masculine and the feminine, the ying and the yang, the effective action, and the compassion. The shape of the Tibetan Dorje is symmetrical, the two pyramidal heads representing samsara and Nirvana, which cancel each other out in its center thanks to the ring of Emptiness. Having a Dorje at home would have positive virtues against the various attacks we suffer.
