Raghuvamsha Sarga 1 | Shloka 17

रेखामात्रमपि क्षुण्णादामनोर्वर्त्मनः परम्।
न व्यतीयुः प्रजास्तस्य नियन्तुर्नेमिवृत्तयः॥

rekhāmātramapi kṣuṇṇādāmanorvartmanaḥ param |
na vyatīyuḥ prajāstasya niyanturnemivṛttayaḥ ||

Under King Dileepa's able leadership, his subjects always upheld the values and traditions of their ancestors just like how (wheels of) a chariot does not deviate from the tracks even by an inch when controlled by an expert charioteer. 

ಹೇಗೆ ಉತ್ತಮ ಸಾರಥಿಯ ನಿಯಂತ್ರಣದಲ್ಲಿರುವ ರಥವು ನಿಶ್ಚಿತ ಮಾರ್ಗದಿಂದ ಸ್ವಲ್ಪವೂ ಸರಿಯುವುದಿಲ್ಲವೋ ಹಾಗೆ ದಿಲೀಪನ ಆಳ್ವಿಕೆಯಲ್ಲಿ ಅವನ ಪ್ರಜೆಗಳು ಪ್ರಾಚೀನ ಕಾಲದಿಂದಲೂ ರೂಢಿಯಲ್ಲಿದ್ದ ಆಚಾರಗಳನ್ನು ಚಾಚೂ ತಪ್ಪದೇ ಪಾಲಿಸುತ್ತಾ ಬರುತ್ತಿದ್ದರು.

some thoughts:

- Although I have used the phrase "... of their ancestors", Kalidasa uses आमनोः to mean since the time of Manu himself.

- On a tangential note, I have always found the word चक्रवर्ती (chakravarti) to be a very interesting synonym for king. One interpretation of the word is -- "one whose wheels are always in motion" i.e. all kings acknowledge his superiority and so, he rules limitless lands. The interpretation that I like better is "one who holds the wheel in place". The king here is like the eye of the wheel that holds all the spokes in place so that the wheel (here, the country) can function smoothly!
