Granted, this is my research and you may find that DeVinci's explanation does not agree yet when you look at the symbolism and numerology (sacred geometry) the connections are there.
In my research on the ken-po goku-i, the I Ching and its relationship to the practice of Isshinryu karate-do not to forget the symbolism Bushi Tatsuo Sensei incorporated in his style there must be meaning that connects everything much like the Universe is made up of connections or strings, i.e. string theory, etc.
The first two precepts of the ken-po goku-i are directly connected to all this and the other six precepts indirectly. If no other reason it is an interesting journey when you start to "see" connections especially in actual practice.
Kanpai Bushi Tatsuo Sensei!
