"Dear Jagannatha Prabhu,
Thank you for the message. Please forward to me when you get the answer, my concern is that with my little knowledge I have noticed that the pranam mantra may need some correction. It has some incorrect composition and some missing letters. In my knowledge I have found the pranam mantra as follow:
Mridanga brahmarupaaya laabanya roso maadhuri,
sahasra-guna samyuktaa mridangaaya namo namah
I hope you will find the correct one. Haribol!
YS"
I got this mantra from my 'siksa guru' (I get lessons on a video)
Namo Jagannatha Sutayo
Namo Mridanga Namaha
Labanga Rasa Madhuri
Sahasra Guna Samyuktang
Namo Mridangaya Namo Namaha
Namo Baladevaya Namo Namaha.
Translation:
I offer my respectful obeisances unto the son of Jagannatha Misra (Lord Caitanya Mahaprabhu). I offer my obeisances to the mridanga from which sweet and necterean sound emanates. I offer my obeisances again and again to the mridanga which has thousands of good qualities. And I offer my obeisances unto Lord Baladeva who assumes the form of a mridanga to serve Lord Caitanya Mahaprabhu.
