Do I need a special talent to be able to learn to do these crystal healing techniques?

The only talents that you need are the interest to learn and the motivation to practice. The techniques, correctly done with the appropriate tools, consistently deliver the described results. Techniques that depend on undetermined innate skills are not published. Techniques that don’t work consistently and reliably are discarded. Techniques that require additional talents – such as well-developed intuitive skills – are reserved for the more advanced courses.
