Explanation: The Himalayas form a formidable barrier against the foreign invasions from the north but it is not altogether secluded from the rest of the world. There are some important passes through which interaction with western, central and northern Asia has been maintained since time immemorial. It is said that 'since early Siwalik times there has been a more or less constant intercourse between East Africa, Arabia, Central Asia and India maintained by the migrations of herds of mammals'. It is also stated that (India) 'received large accessions by migration of the larger quadrupeds from Egypt, Arabia, Central Asia, and even from the distant North America by way of land bridges across Alaska, Siberia and Mongolia'. Besides guarding the northern frontier of India from human invasions the Himalayas protect us from the cold Siberian winds. The great Indus, Ganga and Brahmaputra plains with most fertile land, natural resources and perennial rivers is a gift of the Himalayas, for which Indians gratefully worship it as God.
