After having stopped the lower activities of the mind, it must be made receptive; and, instead of weaving all kinds of empty and idle thoughts, the mind should receive intuitions from above.
There are many virtues in books, but the essential value is the adding of knowledge to our stock by the record of new facts, and, better, by the record of intuitions which distribute facts, and are the formulas which supersede all histories.
