The Big Raft (Tanka)

Great tanka as 5/7/5/7/7 syllables. I think, if I'm not mistaken, there should be some commas to complete the meaning as follows:
Maturity test:
you cease to identify
only your own group,
as containing the essence,
the spark of humanity.

I really enjoyed reading the contents.
