"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."
