Unlike all the other art ...

Unlike all the other art forms, film is able to seize and render the passage of time, to stop it, almost to possess it in infinity. I'd say that film is the sculpting of time.
 Andrei Tarkovsky

Quotes from the same author

Man is born unto the trouble as the sparks fly upwards." In other words suffering is germane to our existence; indeed, how without it, should we be able to "fly upwards".
 Andrei Tarkovsky
MORE CONSISTENTLY THAN EVER I WAS TRYING TO MAKE PEOPLE BELIEVE THAT CINEMA AS AN INSTRUMENT OF ART HAS ITS OWN POSSIBILITIES WHICH ARE EQUAL TO THOSE OF PROSE. I WANTED TO DEMONSTRATE HOW CINEMA IS ABLE TO OBSERVE LIFE, WITHOUT INTERFERING, CRUDELY OR OBVIOUSLY, WITH ITS CONTINUITY. FOR THAT IS WHERE I SEE THE POETIC ESSENCE OF CINEMA.
 Andrei Tarkovsky
MANY MANAGE TO SEPARATE THEIR LIFE FROM THEIR FILMS. THEY LIVE ONE WAY AND EXPRESS OTHER IDEAS IN THEIR WORKS. THEY ARE ABLE TO SPLIT THEIR CONSCIENCE. I CAN'T. TO ME CINEMA IS NOT JUST MY JOB: IT'S MY LIFE, AND EACH FILM IS AN ACT OF MY LIFE.
 Andrei Tarkovsky
AN ARTISTIC DISCOVERY OCCURS EACH TIME AS A NEW AND UNIQUE IMAGE OF THE WORLD, A HIEROGLYPHIC OF ABSOLUTE TRUTH. IT APPEARS AS A REVELATION, AS A MOMENTARY, PASSIONATE WISH TO GRASP INTUITIVELY AND AT A STROKE ALL THE LAWS OF THIS WORLD-ITS BEAUTY AND UGLINESS, ITS COMPASSION AND CRUELTY, ITS INFINITY AND ITS LIMITATIONS.
 Andrei Tarkovsky
Artistic creation, after all, is not subject to absolute laws, valid from age to age; since it is related to the more general aim of mastery of the world, it has an infinite number of facets, the vincula that connect man with his vital activity; and even if the path towards knowledge is unending, no step that takes man nearer to a full understanding of the meaning of his existence can be too small to count.
 Andrei Tarkovsky
