I think that you need to realise that what works for you doesn't necessarily work for everyone. And that people not wanting to jump on board with your passion aren't necessarily on a "lower vibration" or "dislike" you or "not worth being your friend anymore" or "threatened by the radical change you represent".
Maybe they don't feel they have time right now for a meditation class. Yes from YOUR perspective nothing is more important or valuable than this class, but they haven't experienced it so they don't know. There's only so much you can do to try and encourage people to follow a path that was lifechanging for you. I've tried to encourage my friends to listen to the meditations that helped me - so far no one has done so, but at the same time they may come to spiritual enlightenment from a different journey. It's not for me to judge them for not making the same choice as me. It's not a judgement on me what they choose to do or not do.
