Reiki Q&A: Post Class Cleanse?

Hi Jerry, It just dawned on me that we didn’t discuss any post attunement cleanse. Friends of mine who have had level 1 have mentioned this to me and I’ve read that it is crucial. Should I plan to follow the 21 days of cleansing and self practice? I know these things are generally beneficial but I would love to learn your thoughts. Thank you! ~ Kelsey
