Hello friend, nice to greet you. I know the book although I have not read it. My mother, many years ago when I was still young haha initiated in metaphysics and took it upon herself to pass on to me some of her knowledge and habits. She has almost the complete collection of those books
In the 70s and 80s that philosophy was very fashionable, those books no longer come out and are difficult to find. If your mum has it, it's a little treasure.
I've always liked those subjects, they really catch my attention. @lisrl26 🤗
