This is a magical meditation technique meant to cause both internal and external change, and its goal is to limit and drain those things that do not serve you. Constriction pulls away at threads that hamper your growth, day to day experiences, and magical rites while also knocking down the potency of adverse rituals performed against you. Done correctly, this technology has both internal impact and the capacity to cause external change, forcing healing in the areas touched by the troubles brought against you. It inspires regeneration, in a sense, as the troubles brought against you mirror your inner landscape, so resolving the external turmoil causes related chaos inside you to terminate and likewise resolve itself.
In a manner of speaking, this is a kind of serpentine alchemy of the heart, mind, and soul as a means of balancing the microcosm & the macrocosm.
Performing this spiritual alchemy within this context can be quite uncomfortable. It requires a deep awareness of the internal troubles caused by external sources of discomfort. If you are able to face your inner demons, so to speak, the act of doing so then fuels this work. extending your reach beyond the inner sanctum of your mind in turn. Without this understanding & the emotion related to it present, the ritual has no heart for the serpent to encircle and ensorcell.
To begin this process, you must start with meditation. Close your eyes, slow your breathing, and connect with yourself. Feel you rooting into yourself, and as you do so, begin to contemplate what you feel at this time. Become cognizant of all that troubles you, be it ill will, frustration, anger, resentment, sadness, or fear, and seek to maintain this awareness *without falling to those emotions OR walking away*(...this last part is extra important!).
As you face this upset, consider the vectors through which this has made its way into your life. Consider who and what brought it into being, and search for a mental awareness of the threads bound between occurrence and cause. At first, this will make little sense to most people, as we have a way of attributing causality with the wrong people & things. When you have the wrong concept in mind, it won't feel weighty or impactful, but rather like its a "miss". When this occurs, don't get discouraged, as when you do finally stumble across the right connection, you'll feel its weight like a stone. It might take some soul-searching, but that connection will eventually be made.
When it is, its not uncommon for a person to begin to shake uncontrollably. At times, it'll feel like you're about to shake yourself out of your body and mind, and this is very often connected to an internal sense of swirling. Like a vortex just opened up within you and a storm's popped out of it in turn. When this occurs, focus through it, but take this awareness as a clear sign that you are on the right path.
When you've made the leap necessary to create this mental link, this is where the magic begins. Feel the serpentine entity you've made friends with through this work awaken and slither about you. Feel that weight settle upon your crown, shoulders, torso, and lap. Feel the serpent tighten its coils around you, and let this sensation deepen until you feel like you might pop. As you do this, see too that your external troubles are treated in a similar fashion, becoming enwrapped by and encased within a serpent's coils, binding, constraining, and Constricting both the trauma and its cause, grinding both sides of the same coin into nothingness.
When you feel that weight begin to disappear and the serpent's coils loosen about you, stir and stand. Return to your usual state of awareness and begin to ground yourself out. Its not uncommon to be incredibly hungry as a direct result of this work, and if you've done this right, you will not be safe to drive for at least an hour. These states of heightened awareness can be extraordinarily intoxicating, and you do not want to do anything that could potentially be hazardous while you're "high" on spiritwork.
After you've grounded, you should feel like that internal weight has less an impact on you. You'll then be free to go about your day to interact with others, likely with less fear and concern in tow. This process can be repeated until you feel more free of the things that hamper growth.
For weightier concerns and experiences, this will take repeated efforts to fully resolve. The more lightweight issues will often be sorted within one session. This is a relatively simple ritual, but it is not at all easy. Working on yourself in this capacity builds an ability to create manifest shifts and changes within your internal and external worlds alike, and you will find in time that performing this Constriction allows other magical projects to flow more readily.
Blessings to you all, and good luck.
