I've always been a big logic & reason guy so I relate to where you are coming from. The one book that really opened me up to this concept was "Becoming Supernatural" by Dr.Joe Dispenza. It is a heavy read but it contains a lot of the "science" behind LOA including brain scans.
It's honestly really fascinating, once I started practicing manifestation and truly surrendered/ fully bought in a lot of positive changes occurred. Ultimately I manifested something that on paper seemed impossible but did become reality so it's undeniable to me now.
Here's the book in case you decide to check it out: https://www.amazon.com/Becoming-Supernatural-Common-People-Uncommon-ebook/dp/B0746RN3G7
Also pretty much all of the guided meditations he explains in the book can be found for free on youtube rather than paying a bunch for them.
