The Buddhist ritual Phurba is a sacred tool used in Tibetan Buddhism for both meditation and ritual purposes. The Phurba is traditionally made of wood, metal, or crystal, and is considered to represent the power of the Buddha. During meditation, the Phurba is used to focus the mind and cultivate positive energy. In ritual contexts, the Phurba is used to symbolically "pin down" negative forces and energies, and to protect against evil spirits and obstacles. The Phurba is also believed to bring blessings and positive energy to the person who uses it.
