Truth
Yes, there is a Uni-fying Source, call it what you desire, it doesn’t matter. Whatever you believe it to be is just fine. There’s no need to change what you call it, nor to adopt another religion or set of tenets by which to live your life.
Humans seek understanding in all things because they are reasoning creatures. To seek to know is a good thing, it is what sets you apart from the four-leggeds, it is why you are stewards of this Earth.
Experience is what helps you to understand something. Yes, someone can tell you something, they can show it to you, or you can read about it in a book that someone else has written, but you will not know it in its Truth until you have experienced it for yourself.
Each experience you have will help you to more clearly and fully understand the Truth of why you are here and what is unfolding in your life, your world, and the Uni-Verse. Stay open to your life, to your experiences, as much as possible without judgment.
