மழை பெய்தால்தான் பயிர் விளையும்
Mazhai peidhaal thaan payir vilaiyum
Meaning
A crop only grows if the rain comes - nothing flourishes without the right conditions and support behind it.
Story
A farmer planted good seeds and added fertilizer with great care, but the rains failed that year, and despite all his effort, the crop never grew. The next year, with the same effort but good rainfall, the whole field turned lush and green.
Reader's Note
Your own effort matters, but the right conditions and support around it are what let it truly pay off.
