What is the Bhagavad-gita?

General understanding of the masses is that Bhagavad-gita is a holy book of Hindu religion, an armchair book for the retirement years or an ancient scripture full of philosophical intricacies. All these opinions make the Gita more or less outdated in the modern context. But by learning from the authorized sources, one understands that Bhagavad-gita is much more than this: it is a guide book to lead an enjoyable and blissful life. In other words, it is a user’s manual to lead a meaningful human life.
