I will not comment on the videos your using as comparison...there not from my school and thats also been beat to death...and as far as the internal forms (since I'm internal only now this is where most of my research is)...GMS has always given credit to the originators of the forms and even the external froms he always credited the originators ...what I remember, he never said they originated in the temple, but came through the temple in the different areas of china...he even researches himself when he goes over there to verify what GMIe told him.
