This community definitely knows how to create a tulpa. However, the hidden mechanisms behind the forming of that second voice in your head are fuzzy, muddled, and largely unknown. Why is is that the forcing methods commonly used by the community result in successfully creating a tulpa? How does a mind form in the brain in the first place? I will attempt to answer these questions with a theory of my own. This will be a somewhat long read, but I encourage you to stick with it until the end as I have thought about this theory for a long time and am very happy with what I have come up with. You probably won't be disappointed. I believe that tulpas are conscious beings, in the same way that you are. They are full fledged, separate people who just happen to share a brain with someone else. I do not see them as a part or extension of the host's mind. Because of this, there is almost no difference in what a host is and what a tulpa is. A host might see themselves as their body, or brain. This isn't necessarily true. The thing that is "you" is your consciousness. You are nothing more than the totality of your experience, and consciousness is experience. If you are not experiencing or observing anything, you are not conscious, meaning you simply do not exist until you regain consciousness. You are a consciousness inhabiting a brain and body, rather than being your brain or body. Now, what is a tulpa? Another consciousness in that same brain. This means that the basic aspects of existence are the same between a host and tulpa. This includes the manner in which a host and tulpa is formed. A host and tulpa do form in different circumstances, but these different circumstances are different ways of doing the same thing. Before I go on I would like to make it clear that thinking and consciousness are not the same thing. You do not have to be thinking to be conscious. Experience and observation does not require thinking - it is simply taking in information. Now, how does consciousness form in the first place? What creates it, and where does it come from? I believe that consciousness is heavily tied to sensory input. I see consciousness as a tool that is used to effectively take in and organize outside information coming in from the senses. In fact, I see sensory input as being the very thing that creates consciousness. The brain responds to sensory input by automatically and naturally creating consciousness as a way to effectively take in that input. When you are newly born, you aren't quite conscious yet. Your body runs on a sort of autopilot. Through time, as your body takes in sensory input, a consciousness starts to form in response to that sensory input. It gradually gets stronger and more solidified, and is most likely fully "there" by the time you are a toddler. Without sensory input, a consciousness would never form in your brain. Once there is a consciousness that has been established within a brain, all sensory input will by default flow to and be taken in by that singular consciousness. A consciousness can also be described as a sort of "hub", or "observation point". Normally, there isn't any need for more than one hub in the brain, and under normal conditions a secondary hub will never develop - because all input automatically flows to the hub that already exists. This is why most people are singlets. However, one can purposefully create a second hub by doing certain things. A tulpa is simply a secondary hub. As implied before, if all sensory information is flowing into one hub, there will be no room for another hub to develop. The key to creating a tulpa is to redirect some of that input out into "nothingness" - and a second hub will form around that input you are throwing around. Because it is not flowing into the hub that is you, it will force your brain to create another hub to take in that input. The brain is very good at automatically creating consciousness. It will do so very naturally with surprisingly little effort. If you direct input to somewhere other than yourself, the brain will do the rest of the work for you. The brain sees input being thrown around without being absorbed into a hub as unusual, strange, and not quite right, so it will automatically create a new hub to take in that input. When you create a tulpa, one of the first things you will do is create the impression that there is somebody other than yourself in your brain. This creates the initial 'point' for input to flow towards. At first, it is nothingness, but provides somewhere for the input to go. Without creating this 'point' all input will continue to flow towards yourself. This is why talking to oneself doesn't create a tulpa - you're still directing the talking at yourself. Now, what is this sensory input I keep talking about as it applies to creating a tulpa? It is the attention and talking you direct towards your tulpa. This counts as a form of sensory input. Tulpa creation methods used by the tulpa community are doing just this, and that is why these methods work. This is also why narration is by far the most important aspect of creating a tulpa - because narration is the very act of making input flow towards this new point you have created. All tulpa creation methods, as varied as they may seem, all break down to this act of throwing input out towards something you label as "not me". This explains why young or undeveloped tulpas may sometimes come to cease to exist if deprived of attention and forcing for too long. Because the hub that is you has been around for much longer, it will act as the 'dominant' hub in which input more readily and automatically flows into. You will also be the one controlling and using your body, meaning you will have a persistent and guaranteed stream of input. In the beginning, your tulpa relies on you feeding it input to maintain it's consciousness. As sensory input creates consciousness, if a hub is to be deprived of sensory input for too long, it will fade away. There is no reason for a hub to exist with no input coming into it. This theory also explains Dissociative Identity Disorder and traumegenic plurality. DID forms due to someone wanting to escape the traumatic situation they are going through. This makes them wish it were happening to someone else. This act of wishing their life upon someone else is what creates the 'point' I mentioned earlier - another direction for input to flow in, away from oneself. It is possible for this point to receive input without it being purposefully directed - as the trauma victim dissociates themselves from the events, more and more input will start going towards this new point they have created, as all of the input they are distancing themselves from still has to go somewhere. Then, a new hub is created. To sum it all up - the brain creates consciousness in response to sensory input, and directing this input in multiple directions allows for the development of multiple people in one brain. I believe that this is how all plurality works. I hope you found this theory interesting! Feel free to leave any thoughts, questions, nitpicks, etc. below. I'm interested in hearing what everyone thinks about this.
