ततो विवदमानः सन् ऋषिभिः सह पार्थिवः ।अथ मामस्पृशन्मूर्ध्नि पादेनाधर्मपीडितः ॥
In plain words
Then the king, still arguing with the sages, and driven now by his own adharma, set his foot on my head.
Close to the Sanskrit
Then the king, being in dispute with the sages, then touched me on the head with his foot, oppressed by unrighteousness.
