no, intent and invitation is what opens doors, regardless of the tool used. at the basic level the tool is really not even in the equation, its the invitation that has meaning, the tool is just a focal point. but that is what most never consider. im just more old school i guess with this, thats why i dont search for these things. but not knowiing what they truly are is the best reason to proceed with caution to start with.... this is the disconnect from old school to the new way of doing this that ive touched on in other threads concerning psychic abilities. everyone would rather start off at the top instead of learning from the beginning kinda stuff.. but hey like i said everyone has their own ways and ideas of how to do things.... admittedly over and over i dont hunt "ghosts" and i wish all those who do good luck and hope nothing bad comes from it, but there is always a steady stream of ppl who come running for advice on how to fix their carelessness and mess ups....lol
