Tuning forks are a gentle acoustic sound therapy. The vibration of this fork is tuned to the crown chakra situated at the top of the head. Creating a smooth energy flow and a balanced harmonious state. When your crown chakra is open and flowing smoothly we become open to divine energy and receive access to the unconscious and subconscious mind. For best results tap the tuning fork over the crown chakra and move in a circular motion or just hold in the hand. Purple Crown Chakra fork comes in its own pouch with a 7" mallet and stamped 172.06 Hz.
