Receiving attunements/reiju: Students are more or less sensitive to energy, especially as a beginner Reiki student, and will often feel and notice physical, mental, and emotional sensations during the attunement more easily with their Reiki teacher right in front of them performing the attunement. (It also helps their linear mind to trust that something is happening!)
Absolutely! Rather than a couple of weekend courses you will likely pay thousands of dollars for, you can take all the time you need to go through the material and practice while having the support of your Teacher and classmates to connect with. I have had countless students who have taken previous in-person Reiki courses comment on how much more information they received in this course as well as how powerful the attunements were in comparison to the ones they received in person.
