ஆற்றுநீரும், ஊற்றுநீரும் உயரமும் அகலமும் உடைய வாய்ப்பான மலையும், மழை நீரும், அழிக்க முடியாத கோட்டையும் நாட்டிற்குத் தேவையான உறுப்புகளாம்.

ஆறு, கடல் எனும் இருபுனலும், வளர்ந்தோங்கி நீண்டமைந்த மலைத் தொடரும், வருபுனலாம் மழையும், வலிமைமிகு அரணும், ஒரு நாட்டின் சிறந்த உறுப்புகளாகும்

ஊற்றும் மழையும் மாகிய இருவகை நீர்வளமும், தக்கவாறு அமைந்த மலையும் அந்த மலையிலிருந்து ஆறாக வரும் நீர் வளமும் வலிய அரணும் நாட்டிற்கு உறுப்புகளாகும்.

The constituents of a kingdom are the two waters (from above and below), well situated hills and an undestructible fort

This Kural, verse 737, delves into the strategic considerations that go into establishing and maintaining a kingdom. It underlines the importance of natural resources and geographical features in ensuring the prosperity and security of a nation. The verse identifies four key elements that constitute a well-established kingdom. Firstly, it mentions the "two waters", which refers to the availability of water resources from both above (rainwater) and below (groundwater or water from rivers and seas). Water is the lifeblood of any civilization, vital for agriculture, drinking, and various other societal needs. The second element is "well-situated hills". Hills and mountains provide natural barriers against invasions, serve as sources of valuable minerals and other resources, and also influence the climate and water distribution of the region. Next, the verse mentions an "undestructible fort". This symbolizes a strong defense system that can resist any external threats. A fort, in ancient times, was not just a military structure but also the administrative and economic center of the kingdom. It represented the power and stability of the ruling authority. Lastly, the verse indicates the importance of consistent rainfall ("varupunal"). Rain is crucial for agriculture, which was the primary occupation in ancient societies. Regular rainfall ensures a good harvest, leading to food security and economic prosperity. In summary, this verse emphasizes the strategic considerations in the establishment of a kingdom - the availability of water resources, the presence of natural defenses and resources offered by hills, a robust fort symbolizing strong defense and administrative capability, and a favorable climate for agriculture. These factors are just as relevant today as they were in ancient times, underlining the timeless wisdom of Thirukkural.
