English has a major lack of terminology for certain stages of development.
One of the key aspects of spiritual development revolves around our sense of being. Early on, we recognize I Am. I exist. More deeply, we awaken to our nature as pure being, pure consciousness. With Unity, we become all that is. We could describe these as stages of recognition of our being. Iness, Amness, Isness.
But with the Brahman shift, we go beyond all of the above – the existence that arises from the dynamics of consciousness. Consciousness is no longer the knower of its own existence.
Beyond consciousness, the knower becomes Brahman itself. We can be said to be beyond consciousness and beyond existence.
Some describe Brahman as nothing (no thing). Yet it is not emptiness or a lack in any way. It is more than the wholeness of being, the infinity of consciousness. Yet this more does not make it something.
And yet Brahman can be said to have a quality of existence. But it differs greatly from that of consciousness. What does it mean to exist beyond existence? It is a kind of para- or meta-existence. Brahman is itself. Brahman is the knower of Brahman.
And because it is completely inclusive, the opposite of the above is also true. Brahman also has no quality of existence.
Of course, I can write all these things but they are essentially meaningless even in Unity Consciousness. Only Brahman can know Brahman. But I do have readers in Brahman and other readers will be as well. It remains useful to explore. Just try to avoid thinking you know something because you read about it.
