I thought that nature was enough — Pregnancy

I thought that nature was enough ¹
Till Human nature came
But that the other did absorb
As Parallax a Flame－

Of Human nature just aware ⁵
There added the Divine
Brief struggle for capacity
The power to contain

Is always as the contents ⁹
But give a Giant room
And you will lodge a Giant
And not a smaller man

(F.1269/J.1286)
