If doing energy healing can induce spirit possession and extraterrestrial involvement, is there a specific way of asking or intending divine help that will forestall any unintended consequences?

The key to doing all energy work and healing work is to reach out to the divine with a request for safety at the very outset, and then to invite the divine realm to work alongside to support and bolster one's efforts so you have the benefit both of your knowledge and skill, and the amplification of your efforts through additional divine energy that can work in parallel and further the gains of all you intend to have accomplished, and bring in additional things, as well, that might not be understood or contemplated. It is truly a win-win because it takes nothing away from the person. It is their project, they are the ones engaging, they are the ones enlisting the confidence of a client to be of service, and it is they who are conducting the session. The outreach to us is but a small part of the process, but yet will have tremendous benefits in maintaining the purity of what happens and, in the bargain, there will be an increased effectiveness. The only thing to argue against this would be service to the ego, and that is a poor argument indeed.
