so hugely)stood my father's dream
his flesh was flesh his blood was blood:
no hungry man but wished him food;
no cripple wouldn't creep one mile
uphill to only see him smile
Scorning the Pomp of must and shall
my father moved through  dooms of feel;
his anger was as right as rain
his pity was as green as grain
Septembering arms of year extend
Yes humbly wealth to foe and friend
Than he to foolish and to wise
Offered immeasurable is
Proudly and(by octobering flame
Beckoned)as earth will downward climb
So naked for immortal work
Here, “is”; a verb; is being used as a noun. This word is a conjugated form of “to be”, therefore meaning that his father gave away much “existence” or “life”–and to  anyone , considering the fact that “is” is third person verb rather than “am”.
