"I tell you, friend, that it is not possible by traveling to know or see or reach a far end of the cosmos where one does not take birth, age, die, pass away, or reappear. But at the same time, I tell you that there is no making an end of suffering & stress without reaching the end of the cosmos. Yet it is just within this fathom-long body, with its perception & intellect, that I declare that there is the cosmos, the origination of the cosmos, the cessation of the cosmos, and the path of practice leading to the cessation of the cosmos."
It's not to be reached by traveling,
the end of the cosmos —
regardless.
And it's not without reaching
the end of the cosmos
that there is release
from suffering & stress.
So, truly, the wise one,
an expert with regard to the cosmos,
a knower of the end of the cosmos,
having fulfilled the holy life,
calmed,
knowing the cosmos' end,
doesn't long for this cosmos
or for any other.
