In the Spirit of Man written by Dr. Ana Méndez Ferrell, you will discover the anatomy of your invisible being, how you were conceived by God, and the different functions of your spirit, soul and heart. You will learn how to reach your highest spiritual potential, how your Tri-part being functions and interacts in the spiritual and physical dimensions, and the spiritual origins of sickness and health. The Spirit of Man is a true legacy of knowledge that will spiritually develop you in ways you have always longed for.
