govardhana-śaila - Govardhana Hill; jñāne - by the understanding; āviṣṭa ha-ilā - became overwhelmed; parvata-diśāte - in the direction of the sand dune; prabhu - Śrī Caitanya Mahāprabhu; dhāñā calilā - began to run.

Śrī Caitanya Mahāprabhu mistook the sand dune for Govardhana Hill and ran toward it.
