Because it can be done as a technique while ignoring all of the voodoo-mumbo-jumbo. The book linked doesn't discuss the metaphysics. Just watch your breath, then be aware of all of the sensations in your body. Personally I find the metaphysics rather cute.

Of the people that suggested alternative meditation styles, one was modded to 3 points and one was at 1 points.
