நானென்னுஞ் சொற்பொரு ளாமது நாளுமேநானற்ற தூக்கத்து முந்தீபறநமதின்மை நீக்கத்தா லுந்தீபற
நான் என்னும் சொல் பொருள் ஆம் அது நாளுமே நான் அற்ற தூக்கத்தும் உந்தீபற நமது இன்மை நீக்கத்தால் உந்தீபற
In plain words
Every night the ego goes out completely. No body, no world, no name, no 'I'. And in the morning nobody has ever said: for those hours I did not exist. You say instead, I slept well. You were there to sleep well. So when you say 'I', the thing you have always been pointing at is not the one that disappears at night. It is what stayed.
Word for word
That is ever the referent of the word 'I' — even in sleep, where the 'I' has ceased. Fly up, undī! Because our non-existence is absent. Fly up, undī!
