There is a wealth of scientific data on birthmarks and their spiritual origin, specifically the scientific studies done by Dr. Ian Stevenson and Dr. Jim Tucker on reincarnation at the University of Virginia.
The birthmarks that are slightly bloody at birth are of most interest. They have been shown to correspond to fatal and near fatal injury in the past life of the reincarnated soul. The injury to the spiritual body and the negative energy from it, are imprinted on the infant’s body when the spirit enters its new life.
These birthmarks are more than just a mark, they are a sign of the unhealed, spiritual injury. A very close friend of mine was born with a birthmark in the middle of her chest and suffered for years from spinal pain. She was always deathly afraid of handguns, not rifles, just pistols. School medicine never was able to find the source her back pain and it took a spiritual healer to recognize that the birthmark represented the entry wound and back pain was in the place where the bullet lodged in her spine. Healing the spiritual body, eliminated the physical pain.
This story reveals a spiritual law - physical injury can damage the spirit and an injured spirit can damage the body. But the spirit can also heal the body.
