"It would appear that for people of this belief, knot magick is used when they want to cast a spell. Some of the gods they worship have a strong connection to horses so if they have a particular request, plaiting this knot in a horse's mane lends strength to the request. This warlock said it is a benign activity, albeit maybe a bit distressing for the horse owner."
