I copy-paste this conversation between me and a good friend in another site to shed some light towards understanding what I was trying to say:
She:
There is a contradiction : first you say that “the poetry is ability to recognise the most beautiful flower”, then you say “when you individuate yourself”. Do you mean that you are that “most latent beautiful flowers” which you managed to individuate?
Me:
the contrast you see is the purpose of the poem: what you see outside transforms you from the inside insomuch that you do not recognise which is which (in and out). Then the revelation happens: you see what you see outside, is you!!
Like the old song: You are everything and everything is you.

She:
I don't understand this sentences: "Fairness, thus solitude", what do you mean? It doesn’t make any sense to me.
Me:
In the first two stanzas I tried to establish that fairness or beauty, equal, solitude. It is the conclusion the poet insists you to get from them. It means the beauty, fairness in its pinnacle is so individuating (from inside and out) and therefor, so agonising.
