The poem that I've quoted below was printed in a newspaper a few months ago. It's the antithesis of narcissism. It's theme seems to be of contentment to live within yourself, rather than share and thereby verify your thoughts. Ironically, I wanted to post it, because it made an impression on me, which is doing just what it advises against. My mind operates in exactly the opposite way to the one described; I can't imagine being able to live like that.
The poet says that to share your thoughts and feelings is to turn them into a lie. I agree, as when I do so, they are turned into a performance. I don't think that that's what the poet meant, though.
Silentium by Fyodor Tyutchev, translated by Robert Chandler.
Be silent, hide away and let
your thoughts and longings rise and set
in the deep places of your heart.
Let dreams move silently as stars,
in wonder more than you can tell.
Let them fulfil you - and be still.
What heart can ever speak its mind?
How can some other understand
the hidden pole that turns your life?
A thought, once spoken, is a lie.
Don't cloud the water in your well;
drink from this wellspring - and be still.
Live in yourself. There is a whole
deep world of being in your soul,
burdened with mystery and thought.
The noise outside will snuff it out.
Day's clear light can break the spell.
Hear your own singing - and be still.
