Subtle energies permeate or surround not only living beings but are also found in all materials and objects of nature, meaning in the items around us that we sometimes interact with. Their effect on the human energy field can be healing or burdensome. This book highlights the significance of these subtle forces for human health, referencing radiesthetic investigation techniques. Furthermore, it presents numerous examples and practical tips on how to cleanse the energy fields of various materials (metals, stones, wood, minerals, and crystals) from attached burdensome energies and infuse them with life-affirming energies by utilizing one's own subtle energies through specific techniques and tools. Siegfried Grabowski shares his knowledge in this book.
