Xuanzang traveling from China to India.

Chinese Buddhist monk name Xuanzang who was traveling for China to India to learn about Buddhism. He learned about Bodhi tree where Gautama Buddha attained enlightenment. In Xuanzang journey in Western Region, he was also learning about how the system was functioning. One of the things he learns was about the cast system and how it works. For example, Brahman has the highest power than anyone in the society. They are much respected because they did well in their earlier life and they are very pure. Other classes are below Brahman. Moreover, Xuanzang  also observed and learned that in India once women get marry they were not allow to marry, but man can marry as many as they want. Xuanzang journey to India was longer than a decade. However, comparing to today it was very long because today it takes only few hours. Back then everything was longer because of the transportation. Therefore, it was very hard to get connected with people around the world. Today people feel very connected with other people around the world due to advance technology.
