Wow!
Format: Kindle
I picked 5 stars because this was the book I've been searching for! I have been on a quest for enlightenment and spiritual growth for years. And needed a way to wash away the heavy feelings and the "stuck" I was feeling. And wanted to know why the same events kept happening to me. And in just a few pages I was instructed on how to reach the records with ease. I have been in the records a few times now. And have been amazed at what I learned about myself. I thought seeing the patterns would be hard. But it's not. All the information in that moment is right there. And as you unwind the karma allowing, surrender and begin to heal instantly other events that you had the same pattern happening shows up too. And even deeper healing happens. I am now well on my way. After just a few trips to the records I can already feel the positive changes happening. I no longer feel that heavy stuck feeling. I have finally found the peace, love and joy I've been missing in my life. And I think everyone should learn how to do this. For this world and the billions of people who live here needs more love now more than ever. Thank you Melissa for writing a book so easy to use and understand.
Love and Light,
Peace and Love to all.

Wow, informative must for career path
Format: Paperback, Format: Paperback
Great resource for any student, young or old. Solid advice and support continues with bonuses after you read with links and resources. Even some one on one with the author, worth much more than the initial cost of the book. Very informative and uplifting. The author wants to make your career choice path easier. A must have for college bound students. It’s like finding a treasure map to all the right ideas! Front to back a super read. I purchased the physical copy and plan to share it with a high school student.
