Though mainly affects one’s physical fitness, it also play a role in the strength of nature interference. The absorption of outer energy (breath of life) to connect your inner world to the outer world. The acts of inspiring, expiring and everything in between are part of a process that allows one to take in or release the gods. Martial artist use attacks to cause a specific phenomenon to occur, but those whose breathing, movement, body and very existence can cause nature interference are beyond that. An example would be the Shinto practice of banishing evil spirits and other unnatural forces by just clapping. However, this particular skill is something that takes a lifetime to learn.
