God leading South American people to North America - an epic story (8)
I believe the answer is:
ramayana
'an epic story' is the definition.
The definition suggests a singular noun which matches the answer.
'god leading south american people to north america' is the wordplay.
'god' becomes 'rama' (Rama is an example).
'leading south american people' becomes 'ya' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to north america' becomes 'na'.
'rama'+'ya'+'na'='RAMAYANA'
Can you help me to learn more?
(Other definitions for ramayana that I've seen before include "1 28 [EPIC POEM]" , "Indian epic poem" , "Sanskrit epic" .)
