IN PERSON CLASSES

Radiesthesia 2 – The Hebrew Pendulum
October 22, 2025 – 8:30AM to 5:00PM   Rapid City, South Dakota
Pre symposium class before the Radionics Symposium

This class is continuation of the material covered in Radiesthesia 1 – The Subtle Energy Spectrum.

Primary focus will be on the Cylindrical Pendulum, and a specialized variant called the Hebrew Pendulum. We will also learn about the Biometer, room clearing diagrams and tools, and some other concepts from Louis Turenne, Enel, and Jean de La Foye.

The only new required tool is the Hebrew Pendulum. Attendees should bring their tools from the previous class.

Prerequisites for this class are Radiesthesia 1 – The Subtle Energy Spectrum, or Biogeometry Foundation training. I will be conducting an online class later this year that covers prerequisite material for those who would like to attend Radiesthesia 2 in October but haven’t taken Radiesthesia 1 or Biogeometry training.

To Register or for more information about the class or the Hebrew Pendulum, contact Dan Mangum, harmonicenergy@protonmail.com or 509-442-3412 (Calls only. No texts).
