Pattinattar was a 10th c. Tamil Shaivite, and one of the greatest poets of that tradition. Like others in the Siddha tradition, he was strongly against ritualism and the caste system, but we have no details of his personal life, and some scholars have proposed that there were two poets of this name, separated by four or five centuries.

I left the world.
I do not wish the two-fold deeds.
I do not mix with idle, useless men.
I do not listen to their speech.

I touched the state
when only Truth
remains.
I swept away
pleasures and pains.
The Highest
which is beyond the reach
of the four ancient Vedas
came
     here
          to me!
