Apart from the mountain representing something like a big obstacle, I see Jimi the child (as in "Gypsy Eyes" or "Angel") on a beach with his little sand mountain which he chops with his hand and then makes something else.
As well as the big imagery of the mountain, there's the small; might even raise a little sand which also brings up the question of are we, as souls, actually doing anything at all or merely observing what appears to be happening.
