When making use of dark forces or energies of low frequency, such as hatred, envy, resentment, anger or ambition, for personal gain by harming others, then we say that these are negative spells.
There are several reasons why negative spells are performed, for example, desire for power, greed, to obtain benefit, enjoyment, low self esteem, emotional or mental imbalance, pride, revenge, influences, spite and intolerance, among others.
There are different ways to perform a spell, from a simple look or gesture to a ritual, depending on the degree of power and experience of the magician who carries it out, as there are those who perform them very easily and others require more effort.
There are also people who use personal items such as clothing or hair to direct the force and energy toward the person the spell was cast onto and so the entities will recognized the individual by the vibration.
The procedure for performing a spell begins with the development of energy, through a ritual. Then it continues by instructing the entities to retain and then be sent to the person you want (it should be very clear to who it will be sent to) and finally, the person is submerged into energy that prevents him or her from undoing the spell, providing a type of seal, one that only the magician who made it or someone with more power can dissolve.
The permanence of the spell depends on the order that was pronounced while doing the spell, for example, if the spell is directed at a person and their descendants, it will end in the corresponding generation.
