Could anyone please help me understand this quote of Milton from the self-help book "Pushing to the front, Chapter LXII: A College Education at Home" by Orison Swett Marden:
"Books," says Milton, "do preserve as in a violl, the purest efficacie and extraction of that living intellect that bred them. A good Booke is the pretious life-blood of a master spirit, imbalm'd and treasur'd up on purpose to a Life beyond Life."
Thanks
