The reason for writing this book is because of God's irrefutable love for the people of India through His only Begotten son, Jesus Christ.
This book explores the records of archeology, history of migration, language, and religion of Hinduism, and the findings are astonishing in that it is not what we normally expect.
The author described the character and attributes of the six major Hindu deities: Brahma, Vishnu, Shiva, Indra, Krishna, and Rama as written in the ancient sacred Vedic Hindu texts: Rig Veda, Samaveda, Yajur (Black and White) Vedas, Atharva Veda, Upanishads, Bhagavad Gita, Ramayana, Mahabharata, and the Puranas, and they are definitely not as common beliefs or rumors passed down from generation to generation. A comparison is made with the character and attributes of God as described in the Christian Bible.
Similarly, the author explores the origin of Hinduism's major doctrines: Krishna's claims, the Samsara cycle, Trimurti, avatars, dharma, self-realizations, renunciation of and freedom from attachments, yogic meditation, demonic possession, and minor doctrines like worship, idol worship, sin, death incarnation, castes, hell, curses, women, astrology, etc. as found in the ancient sacred Vedic texts as mentioned above and compared them with the theology, doctrines, and practices as found in the Christian Bible.
