The first effect of the mind growing cultivated is that processes once multiple get to be performed in a single act. Lazarus has called this the progressive "condensation" of thought. ... Steps really sink from sight. An advanced thinker sees the relations of his topics is such masses and so instantaneously that when he comes to explain to younger minds it is often hard ... Bowditch, who translated and annotated Laplace's Méchanique Céleste, said that whenever his author prefaced a proposition by the words "it is evident," he knew that many hours of hard study lay before him.

The transition from tenseness, self-responsibility, and worry, to equanimity, receptivity, and peace, is the most wonderful of all those shiftings of inner equilibrium, those changes of personal centre of energy, which I have analyzed so often; and the chief wonder of it is that it so often comes about, not by doing, but by simply relaxing and throwing the burden down.

A genius is the man in whom you are least likely to find the power of attending to anything insipid or distasteful in itself.
