EPTMost of the eastern masters hated him and asked him " Why do you show our secrets to the white men". Then Lee replied - " Are they less human than we are ? " There was a battle between Lee and another student to decide who was right - Lee defeated his opponent very swiftly. This is how all the knowledge was spread out in the world. Same with most of the Indian Yogins, if you check online, you will find out that even Indians didn`t know of the hidden yoga schools until 20 years ago. Same in China, schools like the " Blue Lotus (Very deadly)", " Seven Stars (unknown) ", " Shao Lin (very commercial) " , " Togi (in India, litteral translation - stranglers)" where kept secret but now they show themselves and the knowledge they have gathered for thousands of years, we can only benefit from this!
Thanks.
