He who seeks to approach his own buried past must conduct himself like a man digging.... He must not be afraid to return again and again to the same matter to scatter it as one scatters earth, to turn it over as one turns over soil. For the matter itself is only a deposit, a stratum, which yields only to the most meticulous examination what constitutes the real treasure hidden within the earth the images, severed from all earlier associations, that stand like precious fragments or torsos in a collector's gallery in the prosaic rooms of our later understanding.
