Find your own pathway, adopting your own divination technique, is the best way. As the problem with The N.A.M methodology is that it might work for one person, but not the next. And the next may well get frustrated and walk away from their natural abilities, because some N.A.M teacher is so brainwashed and expects others to be the same.
Think about the first mystics and psychics who walked the earth. So it was different then and abilities were inherent and more second nature. But even so they didn't have The N.A.M menus to choose from! They developed by their own instinctive rules; a technique that has been lost due to the brainwashing of uniform identities.
So our advice, find what works for you, even if it is bits and pieces from every belief system under the sun; bastardise the system and make it your own. Make your own divination tools/system and if it works for you ... don't listen to The N.A.M!
The simple rule of thumb .... if there are snippets and parts of established systems that work for you then use them .... and if you find that your own system is made up of those parts ... then use it, as there is no limits to magick. It works by self belief. - Matthew James
