Hydromancy: The Heidenwulfor Method.
I use scrying and many other forms of divination in order to speak with my gods and goddesses (mine meaning the one's I work with). My method for water scrying is fairly simple, incorporating elements of fire gazing, meditation, and altered states of mind.
First, I go into a small room and turn out all sources of light except for one (this is so you can see what you are doing for preparation). Then, I grab a small black bowl and fill it with clear water, placing this bowl some distance from me so i may see into it. Next, I light a candle and position it so from where I'm sitting (or standing) I can see it's flame in the reflection of the water. I do this due to the fact I have had multiple failures while scrying and fire gazing, and have only found success in the combination of the two. Next, I light sandalwood incense, just to calm and clear my mind. I turn out that one initial light source and begin, positioning myself so I can see the fire and water. I then begin to meditate, focusing on the God or wight I wish to speak with. I invoke them, I ask my questions, if I have prepared an offering I give it. Then, I open my eyes and stare into the flame as well as the water, and I receive my messages and have my conversation. I thank my gods if they have responded to me, and I clean my workspace, putting out the fire and drinking the water.
