Synopsis Indian cultural influence deeply permeated the soul of diverse races and enabled them in many cases, to emerge out of primitive Barbarism. India, thus radiated her cultural influence across the mountains and seas, far beyond the frontiers that nature set up for her, and played a larger part in civilizing Asia than perhaps even Greece did in respect of Europe. This is what we mean by Greater India" Dr. R.C. Mahumdar. Ancient Hindu religious law givers ordained that a person should not cross the seas. This would imply that India shunned all relations with the outside world. But this is not so, for India maintained contacts with its Asian neighbours since Harappan times. Indian traders went to the cities to Mesopotamia where their seals belonging to the period between 2400 B.C. and 1700 B.C have been found. From the beginning of the Christian era India maintained commercial contacts with China, South East Asia, West Asia and the Roman Empire. The Indian land routes were connected with the Chinese Silk Route.
