Several weeks on, it did exactly what it said on the tin - I have stronger innate defenses, I have an easier time connecting with and communicating with spirits, and so on and so forth.
What surprised me is I felt the opening of blocks around my heart center, and my energy has flowed more freely in general. I have spontaneously come to accept things within my shadow I was previously unaware of and had not healed. I have a burgeoning drive toward and awareness of my purpose.
Highly recommended, especially if you plan to work with the watchers as a major part of your path.
