There are two ways to move the ritual file.
1 - Backup the iPad and restore it to the iPhone doing a complete overwrite. Make SURE there is nothing in the phone that is different from the pad.
2 - Temporarily move the ritual to Journal. Load iTunes and copy the file to disk. Move it back. Connect the phone. Copy the file to the phone. It will appear in Journal and you can move it.
Personally, I use #1. A lot.
Take the text and create a text file on your machine. Open iTunes and copy the text file into WP. It will appear in Journal. I also do that a lot.
