Mystical Core 3
3. Although mystics cannot define Ultimate Reality in words, they still use words to point to That which is beyond words. For instance, all mystics agree that, while Ultimate Reality constitutes the true nature of everything, in itself It is nothing.
Neti neti (not this, not that)Upanishads (Hindu)
Emptiness (shunyata)...is the ultimate nature of everything that exists. Lama Yeshe (Buddhist)
The myriad creatures in the world are born from Something, and Something from Nothing. Lao Tzu (Taoist)
It is within our intellects, souls and bodies, in heaven, on earth, and whilst remaining the same in Itself, It is at once in, around and above the world, super-celestial, super-essential, a sun, a star, fire, water, spirit, dew, cloud, stone, rock, all that is; yet It is nothing. Dionysius the Areopagite (Christian)
He is not accompanied by thingness, nor do we ascribe it to Him. The negation of thingness from Him is one of His essential attributes. Ibn 'Arabi (Muslim)
The hidden God, the innermost Being of Divinity so to speak has neither qualities nor attributes. Gershom Scholem (Jewish)
