look into yourself

We started reading about Mencius, an innatist Confucian philosopher. His book seems to be better in explaining things compared to Confucius' Analects book. Here's one of the great passages from the book:

BOOK IV, PART A

4. Mencius said, 'If others do not respond to your love with love, look into your own benevolence; if others fail to respond to your attempts to govern them with order, look into your own wisdom; if others do not return your courtesy, look into your own respect. In other words, look into yourself whenever you fail to achieve your purpose. When you are correct in your person, the Empire will turn to you. The Odes say,

Long may he be worthy of Heaven's Mandate,
And find himself much good fortune.
