Beingness and I Amness
The ‘ness’ extension indicates a quality rather than a statement of existence. Beingness is the essence of Universal Awareness, and I Amness the subjective noticing of the fact of one’s own existence.
When you realise yourself to be a grain of sand on infinity’s shore, all of which is the Self, you’ll realise that I Amness is totally dependent on, a product of, Beingness.
