Lord Master refers to the ruler who governs his subjects and kingdom with an utmost compassion and wisdom. His rule is comparable to the ancient emperors Yao and Shun in ancient China, which, in Chinese classics, are seen as the most typical of the Gold Age governors.
"The Bright King models his rule after Shun and Yao,
His virtues are things his people know little about."
"Thương Minh-Vương bắt chước Thuấn Nghiêu,
Lòng hiền đức nào ai có biết."
(Oracles Volume II- 123 - 124)
In his writings, Lord Master often uses this term to denote those rulers who treat their subjects as their own children and always place their wellbeing above his own.
