I have been following the "metaphysical" path for over fifty years and I am still drawn to the writings of those who speak of their way of
interrupting their knowledge and experiences.
Of all the books I've read thru the years, and believe me , there have been many, I would suggest the following two.
The Science of Mind (SOM) by Ernest Holmes newthoughtlibrary.com...
A Course In Miracles (CIM) courseinmiracles.com...
The SOM introduces you to looking at yourself in a more expanded manner. It establishes the relationship between the Creator and yourself. This was
my introduction to metaphysics. It is considered a classic.
The CIM is advanced, but will be more easily understood if the SOM is studied first. Prophets have said that, in time, the CIM will be more studied
than the Bible and eventually replace it. Don't expect to see this in our life time.
Have studied and taught the CIM I can see that happening. It is a life changer. It is not to be just read, it takes about a year to read and absorb
it. Maybe I should say, start absorbing and understanding. The CIM is an "experience".
If you can find groups in your area in which you can engage that would be of great benefit, especially the CIM.
From the CIM. Nothing real can be threatened. Nothing unreal exists. Therein lies the peace of God.
