Boris Pasternak said this quote

The great majority of us are required to live a constant, systematic duplicity. Your health is bound to be affected by it if, day after day, you say the opposite of what you feel, you grovel before what you dislike and rejoice at what bring brings you nothing but misfortune. Our nervous system isn’t just a fiction, it’s part of our physical body, and our soul exists in space and is inside us, like teeth in our mouth. It can’t be forever violated with impunity.

~ Boris Pasternak

Poetry is a rich, full-bodied whistle, cracked ice crunching in pails, the night that numbs the leaf, the duel of two nightingales, the sweet pea that has run wild, Creation's tears in shoulder blades.

~ Boris Pasternak

Literature is the art of discovering something extraordinary about ordinary people, and saying with ordinary words something extraordinary.

~ Boris Pasternak

About dreams. It is usually taken for granted that you dream of something that has made a particularly strong impression on you during the day, but it seems to me it´s just the contrary. Often it´s something you paid no attention to at the time -- a vague thought that you didn´t bother to think out to the end, words spoken without feeling and which passed unnoticed -- these are the things that return at night, clothed in flesh and blood, and they become the subjects of dreams, as if to make up for having been ignored during waking hours.

~ Boris Pasternak
