Any conversation on Serak/ BN deteriorates rapidly doesnt it!? So.. Gnosis, you are claiming from your personal experience, directly from PDT, himself, that he is the lineage holder of ALL serak in the world? As Taoizt says, i think it is unlikely he would make that claim, but you know different? Knowledge and skill are interesting discussions. You mention platforms. they are i believe important in the De Thouars systems, but may not be in other styles. does that mean they are less skilled, or less able, or less knowledgeable? of course not. to claim that would be foolish. they may have DIFFERENT knowledge and skills and emphasis. I know Walter went to Indonesia and researched different styles so there must have been some there for him to investigate. I have been to Indonesia, and see the lists of styles in various places. I remember seeing serak in the lists.. I believe the evidence from youtube is that there is plenty of serak in Indonesia. Serak is also a style included in many other styles any not always taught as a style in its own right. People calling themselves Guru, Maha Guru, Guru Besar, are 10-a-penny. What those titles also need is a moral spiritual background to them, which some may have. In Indonesia and Malaysia there is a reticence to call oneself a Maha Guru because of the dangers of being challenged or attacked physically and spiritually- there is a lot of black magic out there.. so there may be people who have a level of skill. In the west, there is much more need for people to call themselves lofty titles to show their success and to attain the credit they think they deserve. there have been so many serak/ BN discussions that i do think the topic has been pretty much exhausted in terms of the hissy fits and name calling. oh dont forget the twisting of words and comments to suit your own ends. To continue what Taoizt says, focus on your own training skills and knowledge, learn as much as you can from your teacher, develop as a human being, learn compassion, tolerance understanding and acceptance. it is not, these days, as important to be better than someone else, but to be better than you were yesterday.
