Srimad Bhagavatam Canto 05, Chapter 19, Text 02

SB 5.19.2

arstisenena saha gandharvair anugiyamanam parama-kalyanim bhartr-bhagavat-katham samupasrnoti svayam cedam gayati.
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
A host of Gandharvas is always engaged in chanting the glories of Lord Ramacandra. That chanting is always extremely auspicious. Hanumanji and Arstisena, the chief person in Kimpurusa-varsa, constantly hear those glories with complete attention. Hanuman chants the following mantras.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In the Puranas there are two different opinions concerning Lord Ramacandra. In the Laghu-bhagavatamrta (5.34-36) this is confirmed in the description of the incarnation of Manu.
 
vasudevadi-rupanam
 avatarah prakirtitah
visnu-dharmottare rama-
 laksmanadyah kramadami
 
padme tu ramo bhagavan
 narayana itiritah
sesas cakram ca sankhas ca
 kramat syur laksmanadayah
 
madhya-desa-sthitayodhya-
 pure ’sya vasatih smrta
maha-vaikunthaloke ca
 raghavendrasya kirtita
 
The Visnu-dharmottara describes that Lord Ramacandra and His brothers — Laksmana, Bharata and Satrughna — are incarnations of Vasudeva, Sankarsana, Pradyumna and Aniruddha respectively. The Padma Purana, however, says that Lord Ramacandra is an incarnation of Narayana and that the other three brothers are incarnations of Sesa, Cakra and Sankha. Therefore Srila Baladeva Vidyabhusana has concluded, tad idam kalpa-bhedenaiva sambhavyam. In other words, these opinions are not contradictory. In some millenniums Lord Ramacandra and His brothers appear as incarnations of Vasudeva, Sankarsana, Pradyumna and Aniruddha, and in other millenniums They appear as incarnations of Narayana, Sesa, Cakra and Sankha. The residence of Lord Ramacandra on this planet is Ayodhya. Ayodhya City is still existing in the district of Faizabad, which is situated on the northern side of Uttar Pradesh.
