To heal or treat a human body by a wave generator generating waves of a specific frequency resonating with the human body.

The wave generator has an oscillating element comprising a plate body and a vibration motor attached to the plate body. The plate body consists of a gold thin plate, a platinum thin plate and a copper thin plate, which are bonded to one another with an insulator body in-between. Waves of the specific frequency from an oscillator are generated in the oscillating element in the wave generator. When the wave generator is mounted on a hand of a user, the spiritual energy generated from the hand is picked up by the waves generated from the wave generator to be radiated. The waves are applied to another object to be transferred to the object. Then, the waves outputted from the object is applied to the user's body for giving the user mental stability, facilitating the blood circulation or for accelerating the recovery of an affected part of the user.
