The Himachala (the Himalayan mountains) form the boundary for India on the northern part. What is the inner meaning of Himachala? Hima means ice, which stands for purity and peace. Achala means that which is steady. So, Himachala signifies purity, peace and steadiness. The perennial rivers Ganga, Yamuna and Saraswati symbolise the continuous blood circulation in the human body.
