தானே தானே தத்துவ மிதனைத்தானே காட்டுவா யருணாசலா
தானே தானே தத்துவம் இதனை தானே காட்டுவாய் அருணாசலா
In plain words
What is it? It is itself. That is the answer, and if you wait for more there is no more. Said twice, because there is nothing else to say it about. And nobody can show it to you. It shows itself, or it doesn't.
Word for word
'Itself, Itself' — this is the truth; and you will show it of itself. O Arunachala!
