**newruleSrila Locana Dasa Thakura appeared in this world in 1520 A.D.,   thirty-four years after the appearance of Sri Caitanya Mahaprabhu. Locana Dasa   wrote a biography on Lord Caitanya, entitled Sri Caitanya Mangala, and he   wrote many devotional songs

Srila Locana dasa Thakura took birth in a family of Rarhiya physicians who   resided in the village of Kogram, within the Mahakumar (Katna) district of   Barddhaman. His guru was Sri Narahari   Sarkar Thakura.

His father’s name was Sri Kamalakara Dasa and his mother’s name, Sri   Sadananda. He was the only son of his parents. He was raised in his maternal   grandfather’s home and his education was completed there. He was married at a   very young age. From his youth he was very attached to Sri Gaurasundara and   consequently very disinterested in material life, though he was surrounded by   family, friends and society. In his youth he spent the major part of his time   at his guru’s Sripat, Srikhanda, where he learned how to do kirtana.

Lochan Das was married at a very early age,   according to the customs of that time. Since he had been married so young, his   wife first remained with her parents in the village of Amedpur Kakuta. As he   grew older, Lochan showed a highly renounced attitude to life and spent all   his time discussing Krishna katha with other devotees of Gauranga. As the time   approached when his wife was to join him, her family began to worry because of   Lochan Das’s indifference to material life. They approached his guru Narahari   Sarkar and told him of their disquiet. As a result, Narahari ordered Lochan   Das to go to his in-laws’ home.When Lochan arrived in Amedpur, he was unable   to remember where their house was, since it had been so long since he had   visited. He asked a young girl in the street for directions, addressing her as   “ma”, or “mother”. When he arrived at his in-laws’ house, he found out that   the girl whom he had addressed as “mother” was in fact his wife. From that day   on, he always looked upon his wife as a mother, worshiping Guru and Gauranga   in an attitude of renunciation.

He composed Sri Caitanya Mangala from the diary of Sri Murari Gupta. Murari   Gupta, who resided at Nadia, composed many beautiful verses about the life of   Sri Gauranga. These include the youthful pastimes of Nimai, which Murari Gupta   personally took part in, and His later pastimes in Nilacala, after He accepted   sannyasa, which were narrated by Sri Damodara Pandita. Having heard these   verses of Murari Gupta, composed in sanskrit, Locana das says..”I have become   very attracted and so I have composed them in the village folk poetry meter of   Bengali.” In East Bengal there are many village poets, who sing in various   meters known as Laksmir Panchali, Sanir Panchali and Manasa Bhasan. Locana   Dasa Thakura has composed Sri Caitanya Mangala in the meter of these folk   poems. Panchali contains five various kinds of meters.

Sri Vrindavana Dasa Thakura’s composition on the pastimes of Sri   Gaurasundara was originally entitled Caitanya Mangala, but later on the name   was changed to Caitanya-bhagavata. Those pastimes which were not   described in full by Srila Vrindavana Dasa Thakura, Locana Dasa have described   in his Caitanya Mangala. In the invocation of this work, he has first offered   his obeisances to Srila Vrindavana Dasa Thakura, “Whose   Caitanya-bhagavata has enamored the entire world.”

In his Caitanya Mangala, Srila Locana Dasa Thakura has written: “My hope of   hopes is to be near the lotus feet of Sri Narahari Thakura, to serve and   worship him with my very life. The cherished desire of the fallen Locana Dasa   is to be allowed by the grace of Narahari to sing the glories of Sri Gauranga.   My Lord is Sri Narahari Thakura and I am his servant. Bowing and praying   before him I beg him to allow me his service. This is my only aspiration.”

Locana Dasa Thakura wrote Caitanya Mangala   which tells many pastimes of Lord Caitanya not revealed by Vrindavana Dasa   Thakura or Krishna Dasa Kaviraja. He mentions an especially touching   conversation Sri Gaurasundara had with Vishnupriya Devi the night before He   took sannyasa. Being a talented musician, Locana Dasa told Mahaprabhu’s   pastimes in beautiful poetry filled with fire and rhythm. Common people could   easily understand the divine character of Sri Caitanya and awaken their   religious feelings. As devotees regularly chant the Vedic epics Ramayana   and Mahabharata, Gaudiya Vaisnava’s still wander through Bengal reciting the   Caitanya Mangala.
Locana Dasa Thakura also wrote many songs   praising Sri Caitanya Mahaprabhu, Sri Nityananda Prabhu, and Gauridasa Pandit.   Locana Dasa stresses that raganuga bhaktas must take shelter of Gadadhara   Vrindavanisvari to attain Radha-Govinda prema bhakti. Srila Bhaktisiddhanta   Sarasvati Thakura used to print and distribute Locana Dasa Thakura’s Sri   Caitanya Mangala. Srila Prabhupada was very fond of his bhajans. While   singing Parama Karuna Srila Prabhupada would plunge into the ocean of Gauranga   prema. Prabhupada wrote an extensive commentary on this bhajana: Bhajo bhajo   bhai, Caitanya Nitai, sudrdha visvasa kori … “Locana Dasa asks everyone, ‘My   dear brother, just worship Lord Caitanya and Nityananda with firm faith and   conviction.’ Don’t think that this chanting and dancing will not lead to the   desired goal; it will. It is the assurance of Lord Caitanya Mahaprabhu that   one will get all perfection by this process. Therefore, one must chant with   firm faith and conviction.”

(2) bhajo bhajo bhai,   caitanya nitai sudridha biswasa   kori vishaya chadiya, se rase   majiya, mukhe bolo hari hari
(3) dekho ore bhai,   tri-bhuvane nai, emona doyala   data pasu pakhi jhure, pashana   vidare, suni’ janra guna-gatha
(4) samsare majiya, rohili   poriya, se pade nahilo asa apana   karama, bhunjaye samana, kahoye locana-dasa
(1) The two Lords, Nitai-Gauracandra, are   very merciful. They are the essence of all incarnations. The specific   significance of these incarnations is that They introduced a process of   chanting and dancing that is simply joyful.
(2) My dear brother, I request that   you just worship Lord Caitanya and Nityananda with firm conviction and faith.   If one wants to be Krishna conscious by this process, one has to give up his   engagement in sense gratification. One simply has to chant, “Hare Krishna!   Hari Hari!” without any motive.
(3) My dear brother, just try and   examine this. Within the three worlds there is no one like Lord Caitanya or   Lord Nityananda. Their merciful qualities are so great that upon hearing them   even birds and beasts cry and stones melt.
(4) But Locana dasa regrets that I am   entrapped by sense gratification. Since I have no attraction for the lotus   feet of Lord Caitanya and Lord Nityananda, then Yamaraja, the superintendent   of death, is punishing me by not allowing me to be attracted by this   movement.
Purport By His Divine Grace A. C.   Bhaktivedanta Swami Prabhupada 

Songs                    Purport to Parama   Koruna          Prabhupada:   Parama koruna, pahu dui jana, nitai gauracandra. This is a song by Locana   dasa Thakura, a great devotee and acarya of the Gaudiya-sampradaya. He is   declaring that pahu dui jana. Pahu means lords. Dui jana means two. Who are   the two lords? Nitai Gauracandra. One is Lord Nitai, Nityananda; another is   Lord Sri Caitanya Mahaprabhu. So he says that “These two Lords are very   merciful.” Parama koruna, pahu dui jana. Parama koruna  means very   merciful. Nitai Gauracandra. Saba avatara, sara siromani. Avatara   means incarnation, and saba means all. “They are the essence of   all incarnations.” Saba avatara, sara siromani, kevala ananda-kanda:   “And the specific significance of these incarnations is that to   prosecute their ways of self-realization is simply joyful,” ananda-kanda.    They introduced chanting and dancing. No other incarnation There are   many incarnation, just like Lord Rama. Even Krsna, He taught   Bhagavad-gita. That requires knowledge, understanding. But here Lord   Caitanya, Nityananda, introduced some process which is simply joyful:   simply chant and dance. Kevala ananda-kanda. Saba avatara, sara   siromani, kevala ananda-kanda. Therefore he requests everyone, bhajo   bhajo bhai, caitanya nitai: “My dear brothers, I request you. Just you   worship Lord Caitanya and
Nityananda.” Sudrdha biswasa kori’: “With firm conviction and   faith.” Don’t think that this chanting and dancing will not lead you to   the desired goal. It will because there is assurance of Lord   Caitanya Mahaprabhu that you will get all perfection by this process.   Therefore Locana dasa Thakura says that “You must have firm faith   and conviction.” It will act. Bhajo bhajo bhai, caitanya nitai,   sudrdha. Sudrdha means firm. Biswasa kori’, with faith and conviction. But   what is the process? The process is visaya chadiya, se rase majiya. If   you want to be Krsna conscious under that process, then you have to   give up your engagement of sense gratification. That is the   only restriction. You cannot do that. Then it will be very nice. If   you give up sense gratification and come to this stage, then it is   sure that you will reach to the desired goal. Visaya chadiya, se   rase majiya, mukhe bolo hari hari: “And you have to simply chant   Hare Krsna, ‘Hari Hari,’ that’s all, without any motive of   sense gratification.”    Dekho dekho bhai, tri-bhuvane nai. He   says, “My dear brothers, you just try and examine that within these three   worlds there is nobody like Lord Caitanya or Nityananda Prabhu.” Because,   pasu pakhi jhure, pasana vidare: “Their mercy and qualities are so great   that even birds
and beasts, they are crying, what to speak of human being?”   Actually, when Lord Caitanya Mahaprabhu passed through the forest of   Jharigrama, the tigers, the elephants, the snake, the deer, all joined Him   in chanting Hare Krsna. It is so nice. Anyone can join. Animals can   join, what to speak of human being? Of course, it is not possible   for ordinary man to enthuse animals to chant, but Caitanya Mahaprabhu   did it actually. So even if we cannot enthuse animals, we can enthuse   at least human being to this path of Hare Krsna mantra chanting.   Pasu pakhi jhure, pasana vidare. And it is so nice that even the   most stonehearted men will be melted. Pasana vidare. Pasana means   stone, and vidare. Pasana, even stone, will melt. It is so nice. But   he regrets that, visaya majiya: “Being entrapped by   sense gratification…” Visaya majiya, rohili bhuliya. He’s   addressing himself, “My dear mind, you are entrapped in the sense   gratification process and you have no attraction for chanting Hare   Krsna.”    Visaya bhuliya, rohili majiya, se pade nahilo asa:   “You have no attraction for the lotus feet of Caitanya-Nityananda. So what   can I say? It is only…” Apana karama, bhunjaya samana: “I can simply   think of my misfortune only that Yamaraja, the superintendent of death,   he is punishing me in this way, that he is not allowing me to be
attracted to this movement.” This is the statement of   Kahoye locana-dasa: “This is the statement of Locana dasa Thakura.”   (end)
