Gita is a dialogue between Krishna and Arjun, at the onset of battle at Kurukshetra. The act of a sheperd, a teacher to bring his sheep, his student on the right track. The most powerful component in any battle, or day to day life, is not the resources or weapons that one may have. It is the mind, which holds the reigns, and makes all the difference between success and failure, happiness and unhappiness. It is the mental programming that counts.
