Meditation and the Moon
The energy of the moon can be absorbed through a point along the lower lumber called the “Door of Life.” This is a point between the kidneys that can be stimulated through massage or meditation. Because the kidneys regulate the water element and sexual energy in the body, the Door of Life is a natural point to draw in the energy of the moon. The kidneys can be related to the batteries of the body. When they feel charged up, they can perform their many functions, including the growth of bone marrow.
