Wow, that's impressive PK.
I used to have a bookshop and I had many more books than I have now, lol.
I have a good amount of wellbeing books which will come as no surprise. I have 3 on Claire Weekes. Louise L Hay. Eckhart Tolle. The Dali Lama. I'm a big fan of Paulo Coelho. To mention a few.
I like biographies, classics, books of interest. Cookery books. Music books. Crystals and gems. Yoga.
Do you have the book called The Secret PK, I'd be surprised if you didn't.
Anyway, a few years ago I bought a bookcase. It's a huge piece of furniture with glass doors.
