There are Seven Rays or Sacred Flames which begin your journey to Ascension. The Fifth Ray is often called the Ray of Healing. Hilarion, the chohan of the 5rh Ray was a scientist. He worked with science to bring healing.
Do not equate the science of the Fifth Ray with the science you know today in the medical field. With the Fifth Ray you will come to know science in a different way. It is the science of Truth. Acknowledging the Truth in any situation reverberates through your energy. When that acknowledgment breaks through the un-truth you have been living, Healing occurs.
