Runic divination led to the development of sets of runes designed for use in several such systems of fortune telling, in which the runes are typically incised in clay, stone tiles, crystals, resin, glass, or polished stones, then either selected one-by-one from a closed bag or thrown down at random for reading.
Runecasting works deeply with the subconscious. The rune pouch with its runic symbols represents the entire universe. As one poses a question, one’s entire conscious and unconscious mind is focused toward that question, so that the runelots selected are not truly random selections, but rather choices made by the subconscious.
Your runecaster examines cause and effect and points out a likely outcome. Runecasting is a methodology for examining the path one is on and what the effects might be, by making use of one’s subconscious (i.e. an “intuitive perception”), unfettered by limited conscious belief systems.
The runes can be used to help guide you through problems or issues and help show you what is likely to happen. They’re not a form of fortune-telling and don’t offer exact answers or give you advice – rather they offer different variables and suggest how you could behave if the event does occur. Runes are known for hinting towards answers, but leaving you to work out the details, which is where intuition is helpful. – source: www.holisticshop.co.uk/articles/guide-runes
