What makes a spell or a wish to use magic?
Its basically comprises of 3 parts, intent, focus and energy.
Intent part is basically what you want to achieve. The specific outcome or general outcome as specified. Focus is generally what you do to concentrate on the intent, it usually involves saying things over and over again, or chanting, or some form of ritual. Finally energy, most of the time, it comes from the person him/herself. The longer the ritual/focus the more energy is poured into the spell or wish.
Notice something familiar, prayer is precisely that as well, there is an intent, there is a focus, and the energy is provided by you. Yes, Christians all over will be up in arms reading this, but it really is the situation. If you have the gift of spiritual sight you would be able to see, the energy imparted from a person in a blessing, a prayer. It looks like a small cloud of energy being whatever colour the intent is closest to moving from a person to the intended target.
Whether you are using voodoo, prayer, spells are require intent and focus. The more elaborate the ritua/focus the stronger the energy. Basically, the longer you focus on the same intent the more energy is created. Thats why most prayers fail. The intent is there, the focus is there, but the intent keeps changing by the minute. One minute, you want this effect, one minute you want a variation of that effect. That’s why most prayers aren’t answered. Best way to get a prayer answered? Write it down, draw it out in pictures. The longer you put your mind to precisely the same thought the stronger the energy is created for it. The more people involved in it, having the same thought and feelings the stronger the energy to accomplish the effect. Thats why charismatic services usually have things happening, the singing, the chanting, the heavy music all focus the mind to create one or more effect, be it healing, or influencing people to believe gets greater.
Thats’ why Islam could be potentially more powerful then any other religion. All believers focus on Mecca, all the mental energy saying the same prayers through the world 5 times a day are accumulated in a single black square stone. How can any other religion combine their prayers as effectively as they do? Christianity is so divided into so may groups each believing that theirs is the best. There is no unity sadly.
