I recently met a woman who opened up about her unsettling experience with an energy work practitioner. Just as you’d find in any industry, there is a wide spectrum of energy healers out there (think shamans and Reiki, EFT and shiatsu practitioners). Some of these people are excellent at what they do, but others, despite their intentions, aren’t in the best position to be doing work of this nature.
Since energy healing requires a practitioner to enter your energy field, they need to be incredibly clean and diligent about their healing and self-work in order to take the best care of you. In order to ensure that you're not picking up on your healer's unresolved emotional issues or energetic excess, you should choose someone who has legitimate credentials. You should always feel totally comfortable and confident around your energy worker.
