Suffering comes from desire, according to some dude. I think his name was Tony. I think there may be a difference, though, between desiring what you can't have, and desiring what you can. The latter can be a force of motivation.
If you desire perfection, you are going to suffer.
Even the most "evolved" mystic gets hungry or sleepy occasionally. There's always pain in life - that's a sine qua non of existence.
My view is that anti-natalism is the way forward - if pain is inherent to life, and if childbirth is normally voluntary, then why not forgo children to prevent future generations from needlessly suffering?
One night in long bygone times, man awoke and saw himself.
He saw that he was naked under cosmos, homeless in his own body. All things dissolved before his testing thought, wonder above wonder, horror above horror unfolded in his mind.
Then woman too awoke and said it was time to go and slay. And he fetched his bow and arrow, a fruit of the marriage of spirit and hand, and went outside beneath the stars. But as the beasts arrived at their waterholes where he expected them of habit, he felt no more the tiger’s bound in his blood, but a great psalm about the brotherhood of suffering between everything alive.
That day he did not return with prey, and when they found him by the next new moon, he was sitting dead by the waterhole.
