I already know what it is.
It's not infinity. Infinity is already what we're experiencing. THIS is infinity.
Oddly enough, infinity doesn't last forever. Infinity is finite. Things which are finite are infinite. Things which are limited are unlimited. Things which are limited are unlimited. Forever doesn't last forever.
This is the wisdom of the Buddha, and sages of ancient. The wisdom imparted by the Buddha is "form is emptiness. emptiness is form". Black is white. White is black. It's a hard wisdom to understand.
But know this. When the bodybrain ceases to function - there is not anything left. What happens after we die - is that everything ceases to be, and then there is eternal peace everlasting. When everything ceases, then there is peace that can not be destroyed. There isn't some sort of weird-ass trippy infinity after we die. What we are experiencing NOW is weird-ass trippy infinity. Technically, after we die, that "state" is "unknowable". Technically, after we die, we do not enter a new "state". After we die, there it is a "non-state". BUT, it WILL be peace.
The Buddha describes it like a thorn. People asked the Buddha, after we are gone, how can we have peace? If we are dead, how can we have peace if we are gone? The Buddha stated "It is like a thorn. Life is like a thorn. While we are living, we are in pain. After the thorn is removed, then the pain of the thorn ceases and we have relief. It is the removal of the thorn that causes relief and comfort. It is the absence of the thorn that causes the pain to cease. Like a thorn being removed, it is the absence of life that causes the cessation of pain and suffering."
Do you want to know what happens after we die? Let me try to describe it. After we die, there is quintessential peace everlasting. A state of perfection and awesome balance and equilibrium. Timeless tranquility, paradise eternal. Immortality - your true home and place of never-ending rest. Rapture enlightened. Bliss and harmony which is indestructible. True immutable freedom. Uninterrupted, sublime delight. Joy without end. Immaculate, flawless, pristine beauty. Sublime delight.
GOD. Truth. Heaven. Salvation. Holiness. Enlightenment. Nirvana.
All these words do not do it justice. It is peace, joy, and bliss beyond of our wildest imagination.
I want to make some things very clear. After we die, we are not reincarnated - we do not come back. After we die, NOBODY goes to hell - we all go to heaven/peace/nirvana. Also, all things are temporary. Life doesn't last forever, the universe doesn't last forever, nor does the multiverse last forever. All things are temporary and come to an end, and pass unto eternal peace- THAT'S A FACT.
