That is wonderful you are going to get your Patriarchal Blessing, it can hold such value.
I actually received my patriarchal blessing a couple of months ago, and it was one of the most spiritual experiences I've ever had. The feeling I had is beyond discription and different than the feeling of the Holy Ghost. I know it was truely our Father in Heaven and I wish that I could have felt that way forever.
One other interesting thing...our Patriarch records the blessing with two seperate recorders-just in case one doesn't work, but when he finished, neither one had recorded-the buttons were pressed, but nothing was on the tapes. He said that we could either brainstorm and try to remember the details or he could give me another blessing. He chose to give it again. It was equally beautiful and surprisingly similar to the first one-sometimes the wording was slightly different, but the meaning was the same. Which was astounding b/c it was a long blessing and I dont think he could have possibly remembered everything.
So please know, that it is to you He is communicating, what an incredible experience you are going to have.
