My OPINION here is
That our meditations should only be for our own yes knowledge should be open to all but one cannot just keep on taking something and make it your own
Those who take meditations from this holy place cannot turn around and worship false "gods' or slander this place i find it highly disgusting if a outsider seeks to blasphemy us and then take our knowledge
On a YouTube video years ago when we were still JoS there was this big boy nigar that slandered the jos but turns around and says our magic system works
You cannot bite the hand that feeds you
all this knowledge comes From Satan/Zeus/EA /Shivamahadev/Wodan
And he should be given the gratitude he deserves and His High Priest who give them to us should be shown gratitude

If your friends do wish to join in the future I don't see the harm in them gaining some knowledge but they should be brought to full awareness that this knowledge was provided to them by ZEUS SATANAS AND SHOULD BE GLORIFIED FOR THAT
