Majestic chariot with strong wheels cannot traverse the sea;
Likewise, seafaring boat too will not travel in land.
கடல் ஓடா, கால் வல் நெடுந் தேர்; கடல் ஓடும்
நாவாயும் ஓடா, நிலத்து.
This couplet is under the chapter ‘Knowing the (right) place’ – இடனறிதல். Though a chariot might have string wheels it cannot travel in sea. It will sink. Similarly a boat that travels in sea cannot travel in land. It will run aground. Each is meant to be used in its place. Out of its place, it will become a liability.
