"In his diary, Hsuan Tsang has recorded that India was divided into five divisions or to use his language, there were ‘five Indies': (1) Northern India, (2) Western India, (3) Central India, (4) Eastern India and (5) Southern India and that these five divisions contained 80 kingdoms.... It is true that when Hsuan Tsang came, not only the Punjab but what is now Afghanistan was part of India and further, the people of the Punjab and Afghanistan were either Vedic or Buddhist by religion."
