A ritual tool used for spiritual worship, the Vajra scepter is a combination of two powerful symbols: the diamond and the lightning bolt. The diamond, a substance which cuts but cannot be cut, represents resolute spirit. The lightning bolt, with its overwhelming force, represents great power. Together they represent compassion, the most powerful force of all and the ultimate path to enlightenment.
The Vajra sometimes appears as a Double Vajra, also known as Visvavajra. Depicted as an X or shown in vertical form (like a plus sign), it represents the indestructible foundation of the universe. The Double Vajra also stands for protection, harmony, and all-knowingness.
