It's a really interesting system that I intend to take a class in either this Fall or next. They have Rhythmic Scales like we have melodic ones. While it follows a similar context it is all about subdivision and super imposition of these ideas.
Students of I think Northern Indian music (might be south, i don't know) study without drums for a long time until they master the spoken words of these rhythms. It is extremely practical. I have a video of John McLaughlin with Shakti where the two percussionists trade phrases in "rhythmic scat" that is out of this word in terms of bad assness.
Here is an interesting and informative sight to practice rhythm using this ideology.
