What does meaninglessness mean? It means...
Precisely. A way out...
But whenever you posit an opposite to something, for example: meaning vs meaningless then you have created a dualism.
No doubt. That's the nature of language. Very limited... by meaning.
You propose meaninglessness as being beyond dualism. Bzzzzzzt! Wrong! All you have done is present the opposite to meaning.
Yes, a finger that directly point to the moon. Meaninglessness as a concept is just a concept, but very unusual one that changes its meaning when applied. Like swinging doors. What is meaninglessness from the perspective devoid of meaning?
"Therefore, Subhuti, disciples should leave behind all distinctions of phenomena and awaken the thought of the attainment of Supreme Enlightenment. A disciple should do this by not allowing their mind to depend upon ideas evoked by the world of the senses - by not allowing their mind to depend upon ideas stirred by sounds, odors, flavors, sensory touch, or any other qualities."
Those ideas, what are they beside meaning? People do not attach to sound of world, but to their meaning.
So as long as we are trapped in ignorance and dualism
Where is the duality when there is no meaning?
What is realisation? It is... Oh look, I just reified meaninglessness!
I see no meaning in this, nor do I feel a need to reify it.
