Better than my interpretation.
I equated "sisha" with prosperity, you know how they say people who live in glass building and all. I thought you were hinting towards how constrained these rich people are and they are asking you for something, perhaps help..but it is not clear in this material world.

I liked your "self" version; I should have noted the difference between the first stanza and the last stanza-I thought they were the same until I re-read it.

Please write more. If I see a bad poem, I chose not to comment as I am not a big fan of poems. But few good poems force you to write something and this is one of them. Anybody can appreciate such a poem.
