Of course its not literal (Be the ball!).

Also, I believe that they're the same (Hakuda, Zanjutsu, Kidou, Hohou) on a basic level, its how they use that energy and the philosophies behind them that differ.

They can align the spiritual particles in the air so they can stand on them. Using their Reiryoku to do so isn't an ill-fitting addition.
