The overtones of singing bowls are said to have fluctuations similar to those found in nature, which can be expected to have a deep relaxation effect. I would be happy if you could make more effective use of them in your daily relaxation time by combining the overtones of the singing bowl with a healing voice. We use rare full moon bowls for the singing bowls. I am working with the hope of making it easier to incorporate singing bowls into everyday life, even just a little.
