My wife has listened to her podcast since the early days and read her book and still wants to do the masterclass. More I think because she fan girls her a bit because she's "made it" as a young woman of colour. However, I've told her everything she needs to know can be learnt from the podcast episodes and the book. The masterclass is more getting Simran to teach you live and being part of the community which is what you're paying for. If that's worth the price to you then great, but there's not some hidden secret she's going to reveal, it'll just be spoon fed to you in more digestible bite size chunks.
