Indian rivers play an integral part in enriching the value and heavenly beauty of India. They are our greatest natural assets. There are hundreds of them watering our land and making it green and fertile; they even flow as natural highways linking the towns with the villages. The most eye-catching variety of these rivers is that there are navigable rivers, especially in Bengal and Kerala. Even raging torrents which leap from the mountains down to the deep gorges. Some huge rivers sometimes burst their banks and flood the countryside. And in tribute to their strength and beauty, we have always held them sacred.
