a. Important Role of the Himalayas:
If one can consider Egypt as ‘the gift of the Nile’, one as well calls India ‘the gift of the Himalayas’. In fact, the Himalayas which extend along the north limit of India, play an important part in the life of the India Firstly, the extensive wall of the Himalayas controls the climate India.
Indians are saved from the cold-wave of Central Asia because of the Himalayas. Again, the rainfall of the vast agricultural country of ours is controlled by the Himalayas.
Secondly, though it seems improbable in the present Space-Age, the Himalayas kept our country safe from foreign aggression, to some extent, during the ancient and medieval times.
Thirdly, no one can deny the role of the Himalayas in the cultural life of India. Separated from the other parts of the world by the Himalayas in the north, India has succeeded in developing a civilization peculiarly of its own.
