This book is a short revision of the vast volumes of The Bhagavad Gita for the usage and application of the current generation. The eighteen Puranas and great epics like Ramayana and Mahabharata are practical examples of the application of concepts of the Bhagavad Gita. It is also a condensed version of Vedas and Upanishads. It can address any complicated issue of daily life through various paths and also guide people to surpass life cycles to attain ultimate eternal freedom.
Thus, the Bhagavad Gita is an everlasting guide for righteous people to fight against the unlawful. It is also a guide for people to change their approach to lives for betterment. This is the reason why Lord Krishna guides Arjuna in the Mahabharata – to act and fight against the unlawfulness in place of renunciation, irrespective of the person on the other side – through the knowledge of the Bhagavad-Gita so that no sin is committed.
