Here, in one verse from the Sri Caitanya Chakada, Srila Govinda Das has stated the following:
kapatesvara darsana karila sekale
bhavavese gauracandra dekhi bhavabhole
jagannatha krsnacandra aprakruta rupa
smarana karina prabhu arambhila stotra
mahabhava dekhi nityananda prabhu danda nei
tinigada kari bhangi deleka bhasai
ahamkara soham bhava bhargave srotare
bhasia calila danda taranga vidhire
dandabhanga nadi nama vaishnabe chintile
bhrgura asrama tate se danda lagile
budhalinga pattanare nama sankirtana
anandare nishi puhaila mahajana
pratah kale bhargavire karina snahana
ksetra pathe chale prabhu pramudita mana
(Sri Caitanya Chakada)
Translation: The Supreme Lord along with His associates blissfully spent the whole night at Budha Linga Pattana, performing ecstatic harinama sankirtana. During the morning time, after bathing in the river Bhargavi the Lord then went to take the darsana of Lord Kapatesvara Mahadev.
While getting the darsana of Kapatesvaraji, He reached a height of great ecstatic emotion and subsequently could also see, from a distance, the great eternal transcendental forms of the Supreme Lord Sri Jagannath—Krsnacandra. With intense remembrance of those two great Transcendental Forms, Lord Gauracandra started to recite many wonderful stotras in an extemporal manner (verses based upon the prayer offered to the Supreme Lord). Then He blissfully began to proceed towards Puri.
At that time, while seeing this great ecstatic state of Lord Mahaprabhu, Lord Nityananda Prabhu who was holding His danda (staff) broke It into three pieces and threw It into the river Bhargavi. The mood of “I’ness” and “I am one with the omnipresent The”, along with the danda (staff) floated away in the streams of the river.
In this way, the danda continued to float and finally reached at the bank of the river Bhargavi located near the asrama of Bhrgu Muni. From then on, the Vaisnavas at large named the river as Dandabhanga.
