தூய்மன மொழியர் தோயுமுன்மெய்யகந்தோயவே யருளென் னருணாசலா
தூய் மன மொழியர் தோயும் உன் மெய் அகம் தோயவே அருள் என் அருணாசலா
In plain words
There are people whose thoughts and words are clean. They are soaked in you the way cloth is soaked in dye — right through, no part of them left dry. I am not one of them and I am not pretending to be. Let me in the same water.
Word for word
Grant that I too may steep in your true heart, in which those of pure mind and speech are steeped. O Arunachala!
