nipatan - falling down; saḥ - that; giriḥ - mountain; tatra - there; bahÅ«n - many; amara-dÄnavÄn - demigods and demons; cÅ«rṇayÄm Äsa - were smashed; mahatÄ - by great; bhÄreṇa - weight; kanaka-acalaḥ - the golden mountain known as Mandara.
By constitution, gold is heavier than stone. Since Mandara Mountain was made of gold and was therefore heavier than stone, the demigods and demons could not properly carry it to the Ocean of Milk.
