Thuppaarku thuppaaya thuppaakit thuppaarku
Thuppaaya thooom mazhai.
Rain produces food for those who eat; rain is also food for those who eat — rain is all in all.
உண்பவர்களுக்கு உணவை உண்டாக்கும் மழை, அதை உண்பவர்களுக்கும் உணவாக (தண்ணீராக) இருக்கிறது.
The repetition of 'thuppaar/thuppaa/thuppaa' in the original Tamil is deliberate wordplay — Valluvar says rain is the source of food AND is itself food (water). This single kural captures the entire agricultural and life cycle: rain → crops → food → water = complete sustenance.
