I have a particular system of looking at energy which makes manipulation pretty simple. I describe it as though they are pressure fields. There are two polarities which need to be kept in mind, and the relative strength of each group of energy also.
Masculine, positive, light energy, is one polarity. It’s focus is on pushing. The other polarity is feminine, negative, dark energy. Its focus is on pulling. And then you have the two relative strengths. The strength/pressure of any mass of energy can not be quantified by itself, as the strength/pressure is determined in relation to one or more other masses of energy.
For instance, if you have a mass of energy with a density of 1, another mass with density of 2 would have a higher pressure, and a third mass with a density of 0.3 would have a weaker pressure.
Understanding these two things gives you immense control over energy. Ill go over a few examples that look at both the polarity of the energy, and their density, to determine how they will behave.
In the case of a high pressure light energy, and a low pressure dark energy interacting, the light energy will push into the dark energy, and the dark energy will be turned light. In the case of a low pressure light energy, and a high pressure dark energy interacting, the dark energy will pull the light energy in, and the light energy will be turned dark.
It might initially seem like both interactions have almost the same result, but it isnt the case. Light always pushes, and dark always pulls. However, if one polarity has a much greater density than the other, that polarity will be the only one remaining after the interaction.
So, if light energy with a density of 1 interacts with a dark energy with density of 0.5, the end result will be a mass of light energy with a density of 0.5, as the light energy has to spread itself thinner to fill the mass. And vice versa.
If you can understand this, you will have an advantage when it comes to energy manipulation. Of course, both light energy and dark energy can be programmed to carry out different tasks, or to vibrate in different modalities (the 4 classical elements are a good example of that), but the fundamentals I have shared are the most important.
Examine the energy, and figure out what type of energy he is using. If it is a straight vampiric attack, it is almost certain he sits within a powerful field of dark energy. Of course the strength of the field is relative to the strength of your own field of light energy. In this scenario, you could focus on making your energy toxic towards them, and generating just enough light energy that it is steadily sucked towards him. This will use the strength of the vampiric attack against him, as he will be consuming poison essentially.
If he is using some form of electromagnetism, I would liken that to attack with a field of light energy. In that case you can summon within yourself a powerful field of dark energy to pull that energy into yourself and take it from him. In a sense, perform your own vampiric attack against him.
In fact, after reviewing your picture, it seems like he lodged an attack with light energy against your own system which has damaged some of it, and then he has flooded your system with his own energy as a means of corruption/control. I would surround myself with dark energy for an extended period of time to starve the systems he has put in your body, and draw the energy from it back into your own control.
The real secret (and I can’t believe im sharing this publically, might remove in a few hours), is that if you place yourself in the correct space astrally most of this can be automatic. You don’t have to do the work to summon the correct energy if you just allow yourself to sit in a field of the correct energy. Feel the energy he has placed within you, and isolate it, or fix it in a specific place within the astral. You will want it to be in an area of a weak to moderate field of light energy. Afterwards, take the rest of yourself, and sit within a powerful field of dark energy. Then, just examine the energy he has put into you, from your seat in the astral. The energy will naturally flow from it and into you, like ocean currents almost, or magnetism.
Also, have you used the sigil I sent you?
