Chapter 1 of the Geeta is titled Arjuna Vishad Yoga and Chapter 18, the final chapter is titled Moksha Sanyasa Yoga.

Thus the journey of the soul, as outlined in the Geeta, is from Vishad (State of Despondency) to Moksha Sanyasa (State of Liberation).

The causes of despondency, like greed, anger, pride, envy, jealousy, etc., that lead to a troubled mind may vary from human to human, but the Geeta is the universal remedy that uplifts every human being from the depths of such despondency to the Supreme state of Liberation.

Thus, the study of the Geeta revealed in this book in a simplistic verse by verse explanation, is relevant for every human being who seeks to break out of the bonds of despondency and rise to the state of Liberation.
