One of the ways I like to work with scrying is with spirit communication.
I already have a strong connection to spirits, having always had a natural proclivity toward communicating with them, but what I'm finding with scrying is that this proclivity is further enhanced when working with the right tools.
In my case, the right tools are a combination of candles and black mirror, along with sometimes using additional tools including a pendulum, Tarot, or cowrie shells for divinatory purposes.
I'll also work with specific spirits around specific themes or areas of interest. In the picture above I have a sigil for the goetic spirit Camio that I'm working with for the purposes of enhancing my skills with candle magic and scrying through flame work.
