I was doing some research into Christian mundras (mundra is a yogic word for ritual hand gestures) when I came across an interesting article in Christian Yoga Magazine. Yes, that’s right, there’s a whole magazine devoted to Christian yoga.
Anyway, it explained the Prithvi Mudra and Pran Mudra from a sort of Christianised Hindu perspective which is what I was looking for.
The references to the Law of Attraction and Oprah is probably all you need to figure out where this is coming from theologically. Needless to say I don’t endorse it, but I think it could be interesting to chew over.
