This type of healing does work. As with all healing - the person receiving the healing has to be ready and willing to accept the healing on all levels of their subtle bodies. There are thousands of people who are part healing circles for planetary healing. Prayers can be guided for anything needed in the person's life. There is power in group energy.
Thought is received by the grids with a more powerful pulse if send by a larger number of souls.
Many people start their own healing circles. Perhaps you would like to create a circle of your own. You may contact a healing circle if you wish to request healing-prayer for someone. Humankind has eternally sought inspiration, understanding and healing from stones and circles. Native Americans honor stones as 'the oldest living relatives'.
