Donald B. Carroll spent his career working in Fire & Rescue, as a district chief, academy instructor, and paramedic. During those 30+ years, he raised a family and pursued the meaning of life through extended study into the Cayce readings and other spiritual, scientific, and philosophical materials. Today, he is a popular presenter and writer of metaphysical topics from Cayce to the Kundalini, and is a regular A.R.E. volunteer. He spent more than 10 years researching and writing his first book, Sacred Geometry and Spiritual Symbolism: The Blueprint for Creation. In 2020, Don published his second book, The Spirit of Light Cubit: The Measure of Humanity and Spirit. Carroll is also an international tour leader visiting sites of a spiritual nature across the globe for the nonprofit Association for Research and Enlightenment, and a former Board member. For more information visit http://donaldbcarroll.blogspot.com/
