Invocation and opening verse explained

Chapter one is perhaps one of the hardest chapters in the Bhagavad Gita to understand. The first time you read it, you'll have questions like: Who is this person? Who is that person? Why is everyone blowing a conch shell? What's this guy's name again? And how is he related to this guy? And why does everyone's conch shell have a name?! We'll help break down the first part of Chapter 1 so all of this makes a little more sense!
