This book describes the figures of the Hindu Mythology, why they came and what they have done. It is not the author’s intention to offer any commentary or explanation. That is the philosophical part and it is not attempted here. This work is primarily intended for the second generation of Indian-Americans who may not have the ready accessibility of Indian mythology as their parents had, through stories, narratives and even actual reading of the Purānas during their youth in India.
