I have hit a brick wall in my research into souls and astral beings. To complete my experiment I have to trap a spirit into a crystal in order to forcefully harness its power. The astral nexus I am drawing upon is that of the lower layers. The transmundane beings there appear to consist of dreamers unaware of themselves being out of theirbody and lower energy spirits preying upon them like wolves. However some spirits who live in these subdimensions are extremely powerful and have much more important agendas than lowering themselves like the other spirits do.
Despite all this I would like to experiment with binding magic in order summon some of these beings, binding them into a circle, and then forcing them into a crystal that I have already collected. This can be dangerous, but if done successfully the power from the spirits can be infused into objects in order to strength those that touch them. The aspect in which the energy shall affect is of my own will and shall not be discussed further.
This comes to my questions. If anyone who does read this have experimented with binding magic or intend to, how would I go about doing this? What kind of binding would you use(cords, knots, circle entrappment, ect)? And what could the energy be used for?
