What are Turiya and Turiayatit states?

As Sadhna deepens, thoughts vanish, awareness remains.
As we do further, awareness (knowingness) loses its purpose of being aware, because there is nothing to be aware of, except awareness being aware of itself.
Even that vanishes at some point, and the Absolute gets realized, but in total silence.
Normally we say –
Tamasoma Jyotirgamay. (Take me from darkness (of ignorance) to the light (of awareness), and it is true.
But the further journey takes us even beyond this light and into the abyss of darkness (Shunyata), and that’s where the turiyatit remains (beyond Turiya).
That’s when the whole sansar, the whole universe (or universes), becomes ONE.
Awareness is a silk thread that takes us on a journey into this enigmatic, unknowable state, where even awareness loses its significance.
But awareness does not disappear; it remains hidden as a potentiality, just as a tree is already hidden in a seed, though not perceptible.
“Turiya (the “fourth” state) is the underlying witness consciousness that permeates waking, dreaming, and deep sleep, representing non-dual reality. Turiyatita (“beyond the fourth”) signifies the total transcendence of all states, where even the witness-observed distinction vanishes, merging into non-dual Self-realization. They are often viewed as the same, with Turiyatita being the ultimate, established awareness of this reality.”
