Is there a bookstore in Bangkok with a good selection of esoteric, traditional and metaphysical books in English? Besides the Pali Canon, I am talking about books about yoga practice, Thai massage, works by Mantak Chia (which are Taoist) and things like that. I saw a bookstore at Central World Plaza but is there any other place? I've also bought a few titles near Wat Po temple but these were mostly dedicated to Thai massage only.

have you tired bookazine? , i remember seeing books like this in there

Kinokuniya Books in the Emporium and Siam Paragon has a decent selection of just about everything.
