I heard the Bhagavad Gita described as the “New Testament of Hinduism” on the radio. I have now seen that this description is quite common. Of course all analogies break down at some point, and there are a number of ways in which this is inaccurate.
Since this analogy could really give totally the wrong impression of the Gita to a Westerner who did not know Hinduism, I will write about some of the main differences.
