You are half right. The problem is not the board. The board is just a vehicle for the problematic heart, which always goes seeking what God has forbidden. Look at Eve in the Garden of Eden. God gave her every tree in the garden except the one tree, and which one did she go for? The one tree. Any heart that goes seeking demons (whether she calls them demons, or knowledge, or ghosts, or whatever) will find demons.
No it’s not. It’s just a freaking board. It does nothing. There’s been hundreds, probably thousands, of tests of them. They do NOTHING.
