If you go to youtube and type in Claire Weekes, her books and talks are available through many channels there. She has an excellent program and a soothing voice. Theres also a wonderful guy, aptly named "wonderbro", who draws heavily upon her works. He has livestreams and lots of videos. His emphasis is not on withdrawal but I have found it very valuable.
I also stumbled upon an audio book available for free on youtube called "an untethered soul" by Michael Singer. I've listened to a few chapters and wow, does it resonate with me!
Happy mothers day to all, be grateful for mothers today and everyday, without them we would not exist.
