While doing meditation of Emptiness or Sunyata Buddha reaches a stage where he says there is nothing at all.
He begins with house being empty of elephants,cows, horses etc and then he says there is only this that is not emptiness,namely, the oneness dependent on Sangha.
Then ignoring perceptions of village and people focuses on wilderness. So we regard it as empty of what is not there but as to what remains they understand it is present. That’s how emptiness is born in them - genuine , undistorted and pure.
Then focuses on Earth ,Infinite space, Infinite consciousness, nothingness,neither perception nor non-perception, signless immersion of heart.
It was produced by choices and intentions therefore it is impermanent and liable to cessation. Knowing and seeing like this their mind is freed from the defilements of sensuality , desire to be reborn and ignorance. When they are freed , they know they are freed. Rebirth is thus ended , spiritual journey has been completed.
We see that through meditation on emptiness there is cessation of ignorance possible.
Emptiness is liable to cessation. The ultimate aim is cessation of ignorance, cessation of desire to be reborn. Once cessation of ignorance is achieved there is no rebirth.
Emptiness is a Dhamma like body and it needs to be discarded. I am not emptiness, emptiness is not mine , emptiness is not myself.
Emptiness is born, Nibbana is unborn.
