Some verses and facts from ‘Sri Krishna Arjun Samvada’ (dialogue) written in Bhavishya Malika by the great sage Achyutanand Das ji-
When Arjun questions Lord Sri Krishna about Jajanagra, Sri Krishna while answering to his question says-
“पार्थ बाणी सुणि प्रभु चक्रपाणि बोलन्ति सुणो है
बिर जाजनग्र कथा कहिबा गोगले नसरी हेबो पार।“
“pārtha bāṇī suṇi prabhu cakrapāṇi bolanti suṇo hai
bira jājanagra kathā kahibā gogale nasarī hebo pāra|“
Listen carefully Arjun, the glory of Jajnagra is too great to describe. Words are not enough to describe its greatness. When I (God) will incarnate in the form of Kalkiram at the end of Kaliyuga, the divine Sudharma Sabha will take place on the same holy land of Jajnagra.
In Dwapar Yuga, Lord Krishna had instructed the Pandavas to go to the holy land of Birja Kshetra when the work of establishing Dharma was completed. Birja Kshetra is a historic Birja temple located in Jajnagar.
श्रीमदबैतरणी तटे, कचिल्यता पार्वती।
śrīmadabaitaraṇī taṭe, kacilyatā pārvatī|
Lord Krishna said that all of you Pandavas should visit that holy place on the banks of Baitarani River (old Ganga) where Goddess Beda, Vipra, Varaha, Birja, and Baitarani reside.
भारतर पुण्य पीठ ओड़राष्ट्रभुंइ तामध्यरे प्रभु ऐतेकथा जेबे हुईं।
bhāratara puṇya pīṭha orāṣṭrabhuṃi tāmadhyare prabhu aitekathā jebe huīṃ|
There are many Punya Peeth (holy places) in India. There are many holy lands and divine pilgrimages. Among those spiritually blessed places, on the divine land of Jajnagra many secrets will be revealed at the end of Kaliyuga and the beginning of Satyayuga,
जाजनग्र बोलीजिबे बैतरणी तीरे,
ब्रह्मा शुभस्तंभ स्थापिथिले पूर्बरे।
jājanagra bolījibe baitaraṇī tīre,
brahmā śubhastaṃbha sthāpithile pūrbare|
Lord Brahmaji established a Shubh-stambh (divine holy pillar) in the land of Jajnagar on the bank of the Baitarani River. The pillar established by Brahmaji, Baitarani River (old Ganga), Goddess Birija or Varah Narayan and Triveni Dhar are all present. Goddess Ganga descended on the earth at the same place when Lord Brahma performed the very first Yagnya Anushthan (Homa ritual).
