《管子·势》
创造高度保密的，可以使进军迅速，创造高度明察的，可代替天的启示：在下面查索不得，那就最大限度地向上探索好了。
大周之先，可以奋信；大明之祖，可以代天。下索而不得，求之招摇之下。
Creation of a high level of secrecy can make military advances rapid, creating a high level of clear view can replace all inspiration of heaven:  if one cannot explore what lies below, it is best to make the best of what there is and explore upwards.
