Exploits of Cholas, Pandyas and other South Kings in North
 

According to the Sangam classics, each of the respective rulers of the chief Tamil kingdoms, the Cera, Cola and Pandya, carried his sword as far north as the Himalayas, and implanted on its lofty heights his respective crest the bow, the tiger and the fish. In these adventures which the Tamil Kings underwent for their glorification, they did not lag behind their northern brethren. The very epithet Imayavaramban shows that the limits of the empire under that Emperor extended to the Himalayas in the north. This title was also earned by Ceran Senguttuvan by his meritorious exploits in the north. Names like the Cola Pass in the Himalayan slopes, which in very early times connected Nepal and Bhutan with ancient Tibet, give a certain clue to the fact that once Tamil kings went so far north as the Himalayas and left their indelible marks in those regions.
