Thirukkural – 412
When there’s nothing on offer for ears to feed,
a little shall be offered for stomach’s need.
செவிக்கு உணவு இல்லாத போழ்து, சிறிது,
வயிற்றுக்கும் ஈயப்படும்.
This couplet is under the chapter listening. Listening to your teachers and learning from them should be your first priority. Only when the teaching is over should you even think about food. I borrowed the feed/need rhyme from Dr.G.U.Pope’s translation.
