யானற் றியல்வது தேரி னெதுவதுதானற் றவமென்றா னுந்தீபறதானாம் ரமணேச னுந்தீபற
யான் அற்று இயல்வது தேரின் எது அது தான் நற்றவம் என்றான் உந்தீபற தான் ஆம் ரமணேசன் உந்தீபற
In plain words
So: find out what is here when the 'I' is not. Whatever that turns out to be — and it is not for anyone else to tell you — that is the real austerity. Not the fasting. Not the vigils. Not the years. Being that. That is the hardest thing anyone has ever done, and it is not a thing anyone does. So said the one who is the Self, and who signs his name here as the Lord.
Word for word
If one investigates what remains when the 'I' has ceased — whatever that is, that itself is good tapas. So said Ramaṇēśa, who is the Self. Fly up, undī! Fly up, undī!
