The short version: It's complicated.
The long version: I fell out of Christianity at age 17 because I had hard questions no one wanted to answer, so they asked me to either stop asking or stop coming to church. I spent years and years reading everything I could get my hands on about religion in general and many major world religions in specific, didn't find anything I could agree with or that seemed true to me as-is, and ultimately decided to cobble together my own beliefs from the useful bits I found in others. So now I have a highly syncretic mix of components from many religions (plus some I cooked up myself) that feels right to me. It centers around the idea that divinity is a kind of all-encompassing infinite ur-consciousness/hive-mind of which we are all a part, that the world is an illusion that creates a divide between us (which is why we feel like individuals), but also within us (between mind/thought/idea and feeling/emotion/experience), and enlightenment comes from learning how to heal those rifts and not just realizing or understanding but knowing in your bones that we are one. In short: the truth is love, love is the union of self and other, of mind (intellect) and heart (wisdom), of order/stasis/death and chaos/energy/life, into the unified psyche of one all-pervading ur-consciousness.
Building your own belief system is not a path I recommend for most because it requires a commitment to intense introspection in order to develop self-awareness and a deep willingness or even desire to have your understanding and beliefs challenged and updated with new perspectives and information. But for me anyway it beats being an atheist (I was one for many years, despite my fascination with religion), though I'm not here to convert anyone. This seems true to me, and that's enough.
