Each month, Walker Brents III spins a tale investigating the work of a poet, a philosopher, perhaps a bit of mythology or a vast national epic — or some other subject that holds a fascination for the incurably curious among us.

Today, as the annual frolic known as the Glen Park Festival unfolds just down the block, Walker will muse on the Bhagavad Gita, a tale with uncountable implications, found within the Mahabarata, India’s great religio-mythological epic.
