Everything is at its Acme
Primarily the skill of navigating society successfully. The modern requirements for producing a wise man are higher than those for producing the Seven Sages, and the modern requirements for dealing with an individual are higher than those for dealing with an entire population.
A more specific definition of this skill would be the ability to skillfully navigate professional and social terrain. It is currently more difficult to cultivate a single intelligent man than it was in the past to cultivate seven sages, and it is currently more difficult to deal with a single individual than it was in the past to deal with an entire nation.
सब कुछ अपने परिपूर्ण स्तर पर है; विशेष रूप से दुनिया में अपना रास्ता बनाने की कला। सप्तऋषियों को बनाने के लिए पहले की तुलना में एक बुद्धिमान व्यक्ति बनाने के लिए आजकल अधिक आवश्यकता है, और आजकल एक व्यक्ति के साथ व्यवहार करने के लिए पहले की तुलना में पूरे लोगों की आवश्यकता होती है।
