Shri Narahari Sarkar Thakura was born at Shri Khanda. Shri Krishnadasa Kaviraja Goswami describes that the residents of Shri Khanda formed a branch of the desire tree of love of God. "Shri Khan davasi (the residents of Shri Khanda) Mukunda and his son Raghu nandan were the thirty ninth branch of the tree, Narahari was the fortieth, Chiran Jiva the forty first and Sulochana the forty second. They were all big branches of the all merciful tree of Chaitanya Mahaprabhu. They distributed the fruits and flowers of love of Godhead anywhere and everywhere. [Chaitanya Charitamrita Adi-lila 10:78-79] Shrila Jagannatha das Babaji Maharaj once stated – "Navadwip is the abode of Goloka. Vrindavana is the abode of Gokula. And Shri Khanda is the abode of Vaikuntha."
Shri Narahari Sarkar Thakura participated in all of Shri Gaurasundara's pastimes. Bhakti Ratnakara states: "Shri Sarkar Thakura's glories are most uncommon. In Braja he is known as Madhumati, whose good qualities are unlimited." (thus proving he was not the author of it)
One day, Nityananda Prabhu arrived at Shri Khanda and said to Narahari, "All right, we know who you are. So where's the honey, Madhu' ?" In Krishna-lila, Narahari is the sakhi Madhumati, whose service is to supply honey for Shri Shri Radha-Govinda and Their associates. So he immediately went to a nearby pond and filled a pot which immediately turned into honey of the most nectarean kind. Nityananda Prabhu and His associates drank from this pot to their full and unlimited satisfaction.
Narahari dasa Sarakara was a very famous Devotee. Lochana dasa Thakura, the celebrated author of Shri Chaitanya-mangala, was his disciple. In the Chaitanya-mangala it is stated that Shri Gadadhara dasa and Narahari Sarakara were extremely dear to Shri Chaitanya Mahaprabhu, but there is no specific statement regarding the inhabitants of the village of Shrikhanta. (A.C. Bhaktivedanta Swami Prabhupada. Chaitanya Charitamrita Adi-lila 10:78-79.purport)
Shri Lochana dasa Thakura was the dear disciple of Shri Narahari Sarkar. In his book Chaitanya mangala he introduces his guru in this way: "My Thakur (spiritual master) is Shri Narahari das Thakura, who is very influential amongst the medical caste. He is continuously absorbed in Krishna-prema, and in fact his body knows nothing but Krishna. To his followers he speaks about nothing other than love of Krishna. He was previously known in Vrindavana-lila as Madhumati and was a storehouse of sweetness (honey), and very dear to Radharani. Now he is now present in Kali-yuga with Shri Gaurasundara as Shri Narahari. He is the keeper of the storehouse of love of Radha and Krishna." [Shri Chaitanya Mangal, Sutrakhanda]
This is supported in Gaura Ganod-desh dipika of Kavi-karnapura 177., wherein it is said:
pura madhumati prana-
shakhi vrindavane sthitaa
saarakarah prabhoh priyah
"Shrimati Radharani's dear friend, the Vraja-gopi named Madhumati-devi, appeared as Narahari Sarakaara, who was very dear to Lord Chaitanya".
Shrila Bhaktivinoda Thakura, in his Gaura-arati kirtana, sings of some of that intimate service to that he performed for Lord Chaitanya: 'kiba narahari adikari chamara dhulaya' "Narahari is fanning Gaurasundara with a yak-tail (chaumara) fan."
Shri Narahari Sarkar Thakura was a very expert singer as well as poet. He has composed many songs about the pastimes of Lord Chaitanya and Lord Nityananda. He composed a Sanskrit work entitled Shri Bhajanamrta. Gaurviraha-gita pada kalpataru is also attributed to him, although some scholar Devotees doubt whether it is really his own composition.
Most of Narahari Sarkar Thakura's songs have gotten mixed up with Narahari Chakravarti Thakura's compositions (Narahari Chakravarti Thakura is the author of Bhakti-ratnakara). Therefore is difficult to ascertain which are actually his. Before the appearance of Shri Gaurasundara he also composed many songs about the pastimes of Shri Shri Radha and Krishna.
Narahari was the only Devotee who had the adhikara (right) to do Gaura-kirtana in Gaurasundara's presence. Ordinarily, if anyone would praise Mahaprabhu in His presence, or chant His Holy Name, He would block His ears and call out "Vishnu! Vishnu!" Narahari, however, enjoyed the special privilege of being able to sing about Mahaprabhu in a very unique mood and with sweet descriptions of His transcendental beauty without objection from Mahaprabhu.
His disappearance is on the Ekadasi tithi day, of the dark fortnight, in the month of Agrahayon (Mrigashir – Nov-Dec).
