The following summary of the Eighteenth Chapter is given by Śrīla Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya. In the village of Āriṭ-grāma, Śrī Caitanya Mahāprabhu discovered the transcendental lakes known as Rādhā-kuṇḍa and Śyāma-kuṇḍa. He then saw the Deity Harideva at Govardhana Village. Śrī Caitanya Mahāprabhu had no desire to climb Govardhana Hill because the hill is worshiped as Kṛṣṇa. The Gopāla Deity could understand the mind of Śrī Caitanya Mahāprabhu; therefore on the plea of being attacked by Muslims, Gopāla transferred Himself to the village of Gāṅṭhuli-grāma. Śrī Caitanya Mahāprabhu then went to Gāṅṭhuli-grāma to see Lord Gopāla. Some years later, Lord Gopāla also went to Mathurā, to the house of Viṭhṭhaleśvara, and stayed there for one month just to give an audience to Śrīla Rūpa Gosvāmī.
(Sri Caitanya Caritamrta-------2:18).

Śrī Caitanya Mahāprabhu danced in ecstasy, but when He arrived at Āriṭ-grāma, His sense perception was awakened. Āriṭ-grāma is also called Ariṣṭa-grāma. Śrī Caitanya Mahāprabhu understood that in that village Ariṣṭāsura had been killed by Śrī Kṛṣṇa. While there, He inquired about Rādhā-kuṇḍa, but no one could tell Him where it was. The brāhmaṇa accompanying Him could also not ascertain its whereabouts. Śrī Caitanya Mahāprabhu could then understand that the holy places known asRādhā-kuṇḍa and Śyāma-kuṇḍa were at that time lost to everyone’s vision. He therefore discovered Rādhā-kuṇḍa and Śyāma-kuṇḍa, which were two reservoirs of water in two paddy fields. Although there was very little water, Śrī Caitanya Mahāprabhu was omniscient and could understand that formerly these two ponds were called Śrī Rādhā-kuṇḍa and Śyāma-kuṇḍa. In this way Rādhā-kuṇḍa and Śyāma-kuṇḍa were discovered.
