Vishnu Sharma’s Panchatantra is a common household item in India. I grew up listening to its stories from my parents and in classrooms (as moral education). It was good to read it in original complete detail to appreciate the “story within a story” format that’s also found in contemporary work of Jataka tales.
P.S. Jataka tales migrated with Buddhism to Greece and Egypt, where the format of “story within a story” became even more popular.
