Valmiki Ramayana Sundara Kanda Shloka 1.123 ( Complete - 5.1.123 Valmiki Ramayana) talks of flying mountains in KritaYuga.
पूर्वं कृतयुगे तात पर्वताः पक्षिणोऽभवन्।
ते हि जग्मुर्दिशः सर्वा गरुडानिलवेगिनः।।5.1.123।।
"Formerly in Kritayuga, O dear, mountains were endowed with wings. They used to move speedily in all directions like Garuda and the Windgod." (Translation)
Now what to make of this verse? Because this clearly says that mountains used to have wings in the KritaYuga and it is said in the next verses that those wings were later cut off. How to make sense of this in the context of what we know about the history of mountains? Is the mainstream perception about the history of all mountains wrong or what to make of this verse?
