As a tantric hatha yogi, I want to be initiated into a real Natha lineage and preferably the kanphata lineage (founders of hatha yoga), anyways I'm interested in other natha sects as well.

I have a western tantric teacher but I want to penetrate deeper into the experience of tantra.

My question is this: how hard is it to find or be invited into a natha kaula? Are they open to foreigners? I already know a french friend who's is a kaula and wonder if all kaula's are open to foreigners?

How about aghora? Beside Robert Svoboda I never heard of a foreigner practicing aghora.

Can you also share anything in relation to natha sampradaya? Links, readings, youtube channels or anything is welcome.

Thank you.
