[Daishiman]

The problem is that a lot of those words are only a rough translation, and if you want to understand the concepts more profoundly then you're going to need something more to get by.

The Buddhist Mahayana concept of "emptiness" requires at the very least a few paragraphs to have a grasp, at best a couple of books on your belt. Same with "concentration" (samadhi), "insight" (vipassana), "life-energy" (prana), and so on and so forth.

To the uninformed reader they certainly add that confusion, but for someone versed in Eastern philosophy it's essential that the original concepts be preserved.
