The Code of Manu was written in 500 BC. It is an ancient Indian Brahmanism code, and was a sacred book compiled by priests at the time based on Vedic scriptures and inherited customs. The main axis of The Code of Manu is the four-surname and four-dwelling system. The content includes the creation of gods, marriage, livelihood, fasting, asceticism, and caste system, such as all kind of social behaviors. The norms cover all over the ancient Indian social culture, which is equivalent to the religious and social obligations of people at that time. Buddhism was emerged in between the late Vedic period or shortly after the end of the Vedic period. The initial development of Buddhism broke through the closed system under the Brahman "caste origin myth", that there is natural inequality between human beings. The Buddha paid more attention to practical experience, the changes of life, respect for free will, and advocate the equality of all beings. Buddha believed that only wisdom, comprehension of the truth is the highest law for eternal life. Exploring these major issues, and observing the doctrines change from Brahmanism to the original Buddhism, this study can not only help people to understand how the original origins of human ideology and consciousness were shaped. Those religious entanglement in the bottom of ancient Indian social and cultural soil and were long lasting in thousands of years before and after the Vedic period. We could find how did Indian civilization and human wisdom obtain a linear ascent; Indian society changed from the "Code of Manu" that just merely a collection of human social thoughts and transformed into a world of substantive relief and religion.
