"Thunder in the sky" is an ancient Chinese metaphor for great power, progress, and strength going into action. Understanding the development and practice of power - based on an in-depth observation of human psychology - has been a part of traditional Chinese thought for thousands of years and is considered a prerequisite for mastering the arts of strategy and leadership. Thunder in the Sky presents two secret classics of this ancient Chinese tradition, translated here for the first time. These texts show that the key to successful leadership lies in determining strategies based on a keen grasp of the aspirations, intentions, and abilities of those around you, especially your enemies and allies. The book discusses the subtleties of strategic thinking and decision making, including how to ascertain people's inner states of mind, test subordinates' strengths, anticipate and avoid dangerous situations, overcome weakness in people and organizations and build alliances and oppositions. The book provides a practical and yet subtle course of study on the practice of power.
