"...During that time, I studied a great deal on my own, read many books on a wide variety of topics, and decided what my own personal beliefs were."
I think that this is fairly common for someone who is honestly searching. But, in the end, what has really been accomplished except to take on board another set of beliefs, even if they are "original" with you. Why is it that people, for the most part, feel that they MUST have a set of beliefs? If one were truly courageous and honest in their investigation of what "god" is, then they perhaps may see what happens when ALL beliefs and ALL religions are left behind. Beliefs are imaginary only, created and sustained by the mind, and for the most part blindly followed. Is there "something" that lies beyond the mind, beyond that which would entertain any belief whatsoever? Isn't this worth investigating directly for oneself? A belief arises within "something", yet this "something" usually gets ignored or glossed over as not worthy of attention. This "container" of belief must have some value worth investigation.
Without "beliefs" one is left with nothing to depend on except one's direct experience of what is unfolding right now in this very moment. Without beliefs clouding up the landscape, one is left with no support in interpreting anything at all - instead, one will be left with the "isness" of this very moment, with the "isness" of one's very existence being reflected in the "isness" of the entire creation. In this there is peace, there is contentment, there is fulfilment, and there is the oneness with all that is.
Why are most not willing to entertain such an investigation? Fear; fear that has arisen as a result of past belief systems, and ultimately, a fear of discovering what one really is because that discovery cannot be put into words because it lies beyond the mind. The human mind cannot conceive of an existence which is not mind-based, and as a result, those who are trapped in their minds will continue to ping pong back and forth from one set of beliefs to another, or stubbornly cling to one set. They will continue to be exposed to the dualism of the mind dominated world, ignorant of the unity of all creation, ignorant of their true nature, and ignorant of their wholeness.
