As with other types of magickal work and energy directing, Reiki can be added here. Along with your own energy, you can send the Universal energy of Reiki into your spell and into your end product. You can even go so far as to cleanse all of your pieces & parts before hand with Reiki and then add more energy into it as you’re stirring, chanting, etc. to charge it.

For those who are unaware, Reiki is a type of energy healing. You can find out quite a bit about it in the Healing & Reiki section of MW, where this is an FAQ with threads explaining what Reiki is and is not. It can (and should) be used to heal yourself, friends & loved ones, pets, plants, pretty much any living thing. But, it can also be used as a clearing technique.
