In the video clip that is the subject of this blog entry, Goku says that “Grandpa said never use magic unless it’s to help someone”.
That comment is intriguing in light of the statement made by an actual Kung Fu instructor who said he was told to “Know Magic, Shun Magic”.
The tone of both of those comments is one of absolute certainty that magic does exist. And the people making those statements are not ones whose expertise or competence should be questionable, because one was made by a person who actually teaches Kung Fu, and the other was made by a cartoon character whose dialog according to the claims of the author of this blog, was created by someone who knows about Yin Yang Theory and Kung Fu.
