Is Talos so powerful, that he can make a rock so big that even he cannot lift it?

Sorry I could not resist. I'll come back sometime with a real question/proposition.
Hey, how about Talos himself. We all have heard that Tiber Septim/Talos/Hjalti Earlybeard became a god. But I cannot ever recall seeing anything in the ES lore that describes - in detail - how? The most I have ever seen anyone say is that he somehow combined with Ysmir and Zurin Arctus in some sort of Mythic Critical Mass. Or that he "walked the walk" i.e. acted enough like Lorkhan that he replaced Lorkhan in the mythic.
But I have never seen anyone describe how you can combine yourself with two others to make yourself a god. Do you all jump into a blender at the same time? Step under a big falling rock that squishes you all together? Do a bunch of ogres all grab a leg or an arm and shove you all together in a big scrum? How come everyone doesn't combine themselves into gods? How come everyone doesn't just pretend to be a god so they can replace them and have uber powers?
