What is the theme in The Bhagavad Gita ?

This book takes an in depth look at the position of the warrior put in the position to battle. Unlike many sources that glamorize this subject matter, the unknown author has gone to great lengths to examine the mind of Arjuna. Despite the fact that the entire confrontation is an example of only one case there is little doubt that the extensive coverage of emotions and thoughts that relate to this matter can be applied in numerous other cases.
