Often people ask about Hinduism and the many gods, supreme gods we worship. Sometime it is hard to explain but if there is a question ther emeust bean an answer. So I am putting it the way I was told by a sadhu (hermit/sage), I met in Gaumukh. He said belief is the core of Hinduism, rest are the ways to reach the core.
There is nothing more unpredictable than nature and at higher altitudes it becomes a matter of life or death in seconds. On one of our mountain climbing trips (in Manali) we faced such wrath of the nature. We heard about this peak which is said to have an height of 5000 plus meters and its takes a full day for the summit.
