ahovalam narasimham gatva ramah pratapavan
namaskutya sri nrsimham astausit kamala patim
govinda kesava janardana vasudeva
visvesa-visva madhusudana visvarupa
sri padmanabha purusottama puskaraksa
narayanacyuta nrsimho namo namaste
devah samastah khalu gopi mukhyah
gandharva vidyadhara kinnaras ca
yat pada-mulam satatam namanti
tam narasimham saranam gato' smi
vedan samastan khalu sastragarbhan
vidyam balam kirtimatim ca laksmim
yasya prasadat purusa labhante
tam narasimham saranam gato 'smi
brahma sivas tvam purusottamas ca
narayano'sau marutam patis ca
candrarka vayvagni marud-ganas ca
tvam eva tam tvam satatam nato 'smi
snapne 'pi nitya jagatam asesam
srasta ca hanta vibhura prabheyah
trata tvam eka strividho vibinnah
tam tvam nrsimham satatam nato 'smi
iti stutva raghusresthah
pujayamasa tam harim
puspa vrstih papatasu
tasya devasya murdhani
raghavena kutam stotram
pathanti ye dvijavarah
tesam svargastu sasvatah
The glorious Rama once visited Ahobala, where He saw the deity of Lord Nrsimha. He offered His obeisances to Lord Kamalapati (husband of the goddess of fortune) and prayed as follows.
(1) O Govinda, Kesava, Janardana, Vasudeva, Visvesa (the controller of the universe), Visva, Madhusudana, Visvarupa, Sri Padmanabha, Purusottama, Puskaraksa, Narayana, Acyuta. O LordNrsimha I offer my respectful obeisances unto You again and again.
(2) I have taken shelter of Lord Nrsimha unto whose lotus feet demigods, prominent yogis, gandharvas, vidyadharas and kinnaras, are constantly offering their obeisances.
(3) I have taken shelter of Lord Nrsimha by whose mercy people receive all the Vedas, the essence of all scriptures, knowledge, strength, reputation and wealth.
(4) You are Lord Brahma, Lord Siva and the best person Lord Narayana. You are the master of the Marutas and You are the sun, the moon, air and the fire as well as the Marut -ganas. I offer my obeisances unto You.
(5) I offer my obeisances unto Lord Nrsimha who is the creator, the maintainer and the destroyer of the entire universe. Although You perform all of these three acts simultaneously You are completely beyond these activities. You are the all pervading, unlimited supreme spirit.
Praying this way the best of the Raghus, Lord Ramacandra worshipped Lord Hari. At that time the demigods showered a rain of flowers on the head of Lord Nrsimhadeva.
This is the best of prayers, called pancamrta or five nectars compiled by Lord Rama Himself. One who reads this will be liberated eternally.
