"Another very important feature revealed in Sangam literature is the conception of the unity of the land-mass stretching from the Himalayas in the north to Kanyakumari in the south. In at least two sources, Tamil kings were praised as having had supremacy amidst all the chieftains who reigned in the land between ‘the Himalayan abode of Gods’ in the north and Kumari in the south and the lands which have the sea as the frontier. The northern limit of this cultural unity is often referred to as the Himalayas. Ganges in floods, as well as ships travelling on the Ganges, is among the scenes depicted in Sangam literature. Pilgrims from all over India coming to have holy baths at Kanyakumari as well as Rameswaram (Koti) have been mentioned in Sangam literature. Speaking of Himalayas and Kanyakumari in association, is another hallmark of many Sangam poems. Apart from such spiritual-cultural unity of India depicted in Sangam poems, there is at least one poem that refers to the political unity of India. This poem, from Puranannuru, speaks of a time when the whole of India ‘from Kanyakumari to Himalayas’ was ruled as one nation, unifying the diverse geographical zones of ‘plateaus, mountains, forests and human habitations’ by kings of the solar dynasty, and identifies Tamil kings as descendants of the solar dynasty."
