Uccahaṭṭa (Kurukṣetra)

While Sri Jiva was listening to this story, they entered Uccahaṭṭa in Kurukṣetra. Śrī Nityānanda spoke again: “All the devas along with the tirthas came here to Kurukṣetra. Whatever tirthas are in the region of Brahmavarta (Generally Brahmavarta refers to the area of northern Uttar Pradesh between the Ganges and the Yamunā.) and Kurukṣetra are all present here. Pṛthūdaka and other holy places reside here and serve Navadvīpa.
The fruit attained by living in Kurukṣetra for a hundred years is obtained by residing here for one night. “The devas came here and set up a market (haṭṭa) for discussing Gauranga’s pastimes. Therefore this place is called Haṭṭaḍāngā. By seeing this place, one will receive the ocean of prema. This is one boundary of Navadvipa. Now let us cross the Ganges.”
(Sri Navadvipa-Dhama-Mahatmya, Chapter 10)

Further south is Uccahatta, nondifferent from Kurukṣetra of Brahmavarta. All the demigods reside here, performing gaura-kirtana. Sometimes the residents can hear that kirtana.
Gauranga and His associates stroll in these forests at midday. overcome with transcendental love. When the devotees give just a hint of Krsna’s pastimes. Gauranga begins to sing and dance as He tastes the emotions of Rādhā.
When will I, alone or with the devotees, drown in the waves of the ocean of love for Lord Caitanya? Feeling destitute. I will wander in the forest of Madhyadvipa at midday, meditating on the emotional states of the Lord.
Then the residents of Madhyadvipa will be merciful and show me: “See, here is our Lord Gauranga, dancing with His associates in a grand kirtana in Brahmanagara on the bank of Brahma-kuṇḍa.”
When will I see that astounding long-armed golden form of Gaura, wearing a garland of forest flowers and loudly calling out. “O brothers, everyone together, chant the holy name!”
Just then, Śrīvāsa and the devotees will begin sankirtana. chanting. “Hari! Hari!” Some others may chant. “O brother. chant Gaurahari’s name! Without Gauranga one cannot attain the service of Radha and Kṛṣṇa.”
(Sri Navadvipa Bhava-taranga)

After explaining the glories of Pushkara tirtha to Sri Jiva, Lord Nityananda along with His associates entered Uccahatta in Kurukshetra. Lord Nityananda said, “All the demigods along with all the tirthas have come to this Kurukshetra. All the tirthas from Brahmavarta and Kurukshetra stay here. Everyone, including Prithudaka, resides here and they easily engage in the service of Navadvipa-dhama. Whatever benefit one derives by residing in Kurukshetra for one hundred years, can be achieved just by spending one night at this place.” Nityananda Prabhu said, “The demigods used to gather here to enjoy gaura-katha, opening the market (hatta) of the holy name here. Therefore this place is known as Hattadanga. Whoever takes darsana of this place achieves unlimited love. Dear Jiva! This is the border of Nadia. Let us now go to the other side of the Bhagirathi.”
In the Mahabharata, Kurukṣetra-māhātmya, the great sage Pulastya says, “O Rajendra, please go to Kuruksetra, which fulfills all desires. By seeing that place all living entities are liberated from their sins. Whoever continually says, I will go to Kurukṣetra, I will live in Kuruksetra.’ will be freed of all sins. If the dust of Kuruksetra is raised by the wind and falls on the limbs of a sinner, that sinner will attain the highest abode.”
(Sri Navadvipa-Dhama-Mahatmya, Pramana-Khanda, Chapter 3)

In the fourth chapter of the Bhagwat Geeta it is affirmed by Lord Shri Krishna that formerly (some 40 crores of years before the battle of Kurukshetra) the mystic philosophy of Geeta was once explained to the Surya God. The message was received through a chain of disciplic succession. But in course of time when the chain was broken by some reason or other Lord Shri Krishna appeared again in the battle of Kurukshetra and taught Arjuna again the self-same truth of the Bhagwat Geeta.
