Below the highest sphere four Regents sit
Who rule our world, and under them are zones
Nearer, but high, where saintliest spirits dead
Wait thrice ten thousand years, then live again;
And on Lord Buddha, waiting in that sky,
Came for our sakes the five sure signs of birth
So that the Devas knew the signs, and said
"Buddha will go again to help the World."
"Yea!" spake He, "now I go to help the World.
This last of many times; for birth and death
End hence for me and those who learn my Law.
I will go down among the Sakyas,
Under the southward snows of Himalay,
Where pious people live and a just King."
