The nature of mass

"Mass is the fulcrum of mobility; stillness is the father of motion. Therefore the sage King, though he travel afar, remaineth near his supplies. Though opportunity tempt him, he remaineth quietly in proper disposition, indifferent. Should the master of an host of chariots bear himself frivolously? If he attack without support, he loseth his base; if he become a raider, he forfeiteth his throne."
