Story of King Bhagiratha and Ganga

King Bhagiratha does tapas to petition Lord Siva to allow Ganga to come to earth, but the earth cannot bear the torrential flow of water from heaven. Lord Siva catches Ganga in His hair, and from there she flows to earth.

The Saiva Siddhanta perspective is that Siva's wonderful universe of form is perfect at every point in time, complete and totally just, and every soul, in all stages of evolution, is an intrinsic part of it, even Siva himself.
