Sirandha mazhaiyum malaiyum nillaadhu Marandhaar kann maaivadhilai.

If rain fails, there will be no grass; if there is no grass, there will be no cattle; if there is no cattle, there is nothing.

(மழை இல்லை → புல் இல்லை → கால்நடை இல்லை → வாழ்க்கை இல்லை என்ற சங்கிலி தொடர்பை விளக்கும் குறள்)

This kural traces the cascade of failure: no rain → no grass → no cattle → no butter → no sacred fire → no rain prayers — the entire cycle collapses. Valluvar shows that rain is not just one element but the keystone of the entire ecological-social-spiritual arch.
