But you have to consider how powerful the Thu'um is. When you go to High Hrothgar, all the other Greybeards besides Arngeir will greet you with nothing except a hushed "Dovahkiin...", and even that's enough to make the whole building tremble.

However, there is one possible way of keeping the Thu'um in check; teaching its users to speak the dragon language. This guy on the TV Tropes "Headscratchers" page for Skyrim goes into more detail: ...the power of the Thu'um is not based on the dragon language; the dragon language focuses'' the Thu'um. Its the difference between a controlled gunpowder reaction in a firearm to direct a bullet, and an uncontrolled gunpowder cookoff.''
