I have come across the following verse in one website.
sundare sundaro ramah sundare sundari katha sundare sundari sita sundare sundaram vanam, sundare sundaram kavyam sundare sundarah kapih sundare sundaram mantram sundare kim na sundaram.
In the Sundara Kanda, or the beautiful chapter, beautiful is Rama, beautiful is the story; Beautiful is Sita Devi, beautiful is the Asoka Vanam; Beautiful is the poem; beautiful is the kapi Hanuman; Beautiful is the mantra; what is not beautiful in Sundara Kanda?
Can anybody explain who wrote this verse? And, out of various beautiful aspects, which one is more appropriate in naming this Kanda as such?
