Magic - White and Black
We know from our daily experience as well as research, that our energetic and emotional field is much bigger than our physical body and influences other people. It's the reason, why it is more fun to watch sports or a movie together and vice versa why fear is infectious and can trigger a panic. As we know from our sources that other realities are non-local, a positive or negative influence can be exerted at a distance, in particular when thoughts are focused as in a laser.
This is the process of 'magic'. The difference between white and black magic is not only the intent, but also essentally respect or disrespect for the frree will of the target.
Pure white magic, healing, benevolent prayer will not only aim to support, help or heal but always be an offering and not a mandate.
Black and grey magic on the other hand is defined by the very intent to manipulate the target according to the will of the practitioner. .
Rituals are frequently used in both forms, in order to assist with the focusing of thoughts, with the ones in black magic being usually more elaborate, as a greater force has to be generated to subdue the will of the recipient.
Assistance by spirits is for the same reason more important in dark magic and calling and 'paying' them is generally part of the ritual. In white magiic/prayer/healing frequently benign entiies join to assist - called or uncalled - but as the process is in alignment with universal law there is no 'friction' and all energy serves the objective.
Targeting is another part, which is more essential to dark magic. As DNA is linked to the soul, anything containing it can be used eg blood, hair, piece of clothing, etc. which - btw - is the same reason, why every 'demonic pact' is signed with blood.
Psychokinesis is another - modern no frills - form of black magic, which is much cherished by secret services. As gifted psychics can heal a body, they can also shut down vital functions to harm or kill a person in an untraceable manner.
