This helpful handbook explains what a reagent is, how they are used in radionics, and gives the reader creative ideas to apply to their own radionic work. Many examples of reagents and a wealth of information about them are provided. Symbols, colors, sounds, Sacred Geometry, and more. This book includes a chapter on crafting your own personal reagents. This is the first book in a series of handbooks designed to help educate radionic practitioners in areas that are not heavily covered in classes or other literature. Applicable to users of Hieronymus, Base 10, Base 44, or other types of radionic instruments.
