Transmutalism

In case you didn't know, transmutation is nothing but transformation of one substance into another. So basically, human transmutation is the (attempted) transmutation of humans and human material.

Maybe the true meaning of Existence is to find Inexistence

Neter Neteru... In old hieroglyphic Egyptian, 'Nada Nadas', 'Não há deuses', ou 'Os deuses são Nadas'. São aqueles que deixaram a sua Consciência Individual e a fundiram no Todo. 'Gods are No-Things', they are those who have left their Individual Consciousness and merged it into the Whole.
God and Nothing is equal.
God (or Gods) and Nothing (or Nothingnesses) is the same.
I could say Nothing in the plural ('Nothings' or 'Nothingnesses'), but it does not make sense because plural is consequence of several individuals - and every being who left his individuality and merged in the whole does not differ [anymore] from any other being who did the same. The multiplicity (consequence of individuality) finally Ended 'there'.
Não existem mais Vários, mas apenas Um. Um que também já não existe e onde todos são o Mesmo.
'Aí' acabaram os números.
There are no more Various, but only One. One that no longer exists and where all are the Same.
'There' the numbers Ended.
There is only one God, is the same as Nothing.
The greatest challenge to Being is to stop Being.
O maior desafio ao Ser é deixar de Ser.
I believe in No-thing.
Eu acredito em Nada.
Eu serei o Tudo para ser o Nada. Já o sou, mas então Sabê-lo-ei.
Ser o Nada e manter o Nada.

'Desejar apenas o Inatingível.'

"I never liked to exist, but in a few moments," few "moments felt good ... But I always wondered: would not it be better not to exist? And the answer was always the same: To not exist!"

"What interests to shave / if it's all to crease / from the toenails to the sovereign mirrors - Leonardo, Camões, Newton, Amadeus Mozart / et cetera / what interests?" Yes, what does it matter? ... " (H. Helder)

I would content myself with attaining Sentience.

The erudite man is a discoverer of facts that already exist - but the wise man is a creator of values ​​that do not exist and that he makes exist. (A. Einstein)

Without your illusions you can continue to exist, but you cease to live.

"Just as a red, blue, or white lotus flower - born in water, grown in water, rising above water - remains unheard of by water, just as I am - born in the world, grown in the world, overcome the world - live without being troubled by the world. Remember me, brahman, as "awake."

"The fermentations by which I would go to a deva-state, or would I become a gandhabba in heaven, or would I go to a yakkha state and a human state: Those were destroyed by me, ruined, their rods removed. insensible to the water, insensitive I am for the world, and so, Brahman, I am awake ". (Buddha)

"this absurd choice of people in choosing nothingness should disturb us" (St. Augustine)

Wrong:
"Thus every desire of the one who wants to die is directed, not to cease to exist by death, but to find tranquility." And so, while mistakenly believing in non-being, his nature is aspiring for tranquility, that is, desire to have a more perfect reality. " (St. Augustine)

NO, no matter how perfect a new reality could be, it would never be perfect - and stable - so, Nothing it would be preferable. No-Existence.

"(...) Therefore, just as it can not be at all believable that someone would like to not exist." (S.A.) - False.

Nothing. Existence has no reason to exist. There is nothing that justifies existence in place of non-existence.
