"Realizations" and sudden understandings of the Nature of God or other spiritual matters often strike, like lightning, quickly, and then we're left with the imprint of it on our minds as the brightness of lightning is left on our retinas, and then we forget it somewhat.
This happened to me yesterday. I had a flash of insight, a direct knowing of something about the Holy Trinity and why Trinitarian theology has been held in Christianity for so long- only for the reflection of that knowing to be virtually unable to pass my lips.
I've been unable to clearly formulate the thought. I've been unable to clearly explain it. Oh, yes, I'm going to try, right here, but it's going to be bungled and muddy and not at all what I want to say. Being the person I am, that's not going to stop me from making the attempt, so please bear with me.
The normal issue we have when it comes to discussions about Self and Other and so on is the degree to which the Self or Other is really something like an illusion OR whether they're, in reality, unified. Is the Self illusory, and only the Objective World real? Is the Objective World a kind of illusion produced by the Self? Are they really united as One beyond all things?
And these things are kind of abstract, philosophical, and the sorts of things that high-level-achievin' meditators discuss and write treatises on.
But the Holy Trinity solves this problem by pointing out that there's always a Third Connection. Even if the Self and the Other are UNITED, there's always a "Third Observer."
In other words, the answer to the question in Buddhism about "Who watches the Watcher?", that is, what is aware when there's no Subject to be "aware of" itself, is the "Third Person of the Trinity." There's always a Third Observer, a Third Person, a Third Reality that is connected to both of the Other Realities.
The Trinity is a Mystery, but increasingly, I understand why it's to be found in Christianity.
