Into the Haunted Ground

It's hard to put my finger on but there are disconnects for me between what the title says, the chapter titles say, and what's actually presented in the chapter.

I can't seem to see the connection between the reference to ‘haunted grounds' and the subject presented in the chapters. Or between the practice of Chod and the subjects presented in the chapters.

It's like there are mentions of Chod but not real details for me. And very little about how the subjects of the chapters actually relate to haunted grounds. I'm sure others will see this but I can't.
