Christians call it Union with God,
Buddhists call it Nirvana,
Hindus call it Moksha or Union with God (of the Atman with Brahman)
...all of these refer to the ability to merge relative with absolute...all "things," all concepts with no thing and no concept. Particles with waves.
Of course we cannot forget concepts and things, we live in that objective reality; our mind has evolved to perceive particles/things/concepts. Our language snatches them out of endless possibility and offers them up for everyone to consider.
But the greater reality is that which precedes objectification, the Kairos...the eternity of the subjective, the possibility of that which cannot be named without limiting. Unknown is always greater than Known.
G_d, the breath of Yahweh...Allah...these are spoken symbols of the sound of our breathing, not objectified designators of some mental concept. These are the sound of Spirit - the sacred no thing and everything. Breath of Life.
Where do we find this no thing? Look within and everything without will be understood.
“The more you know yourself, the more clarity there is. Self-knowledge has no end - you don't come to an achievement, you don't come to a conclusion. It is an endless river.”
~ Jiddu Krishnamurti
