i follow a more buddhist belief. i didn't ask to be made, nor will i ask to die. when it happens,itll happen. The things that make up me will go on, and the things that make up me may be "reincarnated" but like, all that matters is how i act in this life. the promise of a good afterlife shouldn't be the motivation to help you better youself and others spiritually. it should be something done by you willingly.
But like, in regards to the topic, if you think about it, buddhists view enlightenment as extinguising of desire. when you achieve this state, then you are liberated from the cycle of death and rebirth. so in essence, they yearn for the "nothingness" you describe. Just an interesting take on it
