Assuming you've been following only this guide, you've been using your mind's ability to quickly generate thoughts in order to jumpstart the process of getting responses under your tulpa. This engine to produce thoughts is great, because it feels independent from your mind and is easy to kick into action, but it will often fail to produce thoughts which are more complex. While you may be able to hold a conversation with your tulpa using these sorts of responses, you are likely to notice that the responses you receive are inconsistent and lack thought. This can be solved by learning to listen to your tulpa think, allowing your tulpa to produce responses with the same engine of thought that your own idle thoughts derive from.

Inside of your mind, your thoughts are likely running in a constant loop of self-evaluation. You have thoughts, you listen to those thoughts, and you think new thoughts based on what you did just a moment ago. Up to this point, you've likely never had thoughts associated with your tulpa fall under this loop. Instead, you likely consider almost all of the actions of the mind as yourself, and only the special cases where a thought is generated in association to your tulpa as not yourself. Due to this, when your mind sets about processing and understanding the context of a thought which fell under your tulpa, you experience it as yourself explaining and rationalizing why your tulpa did what it did. If you learn to sit back and allow this process to be associated with your tulpa instead of yourself, you should experience your tulpa being able to take a thought, look it over, and expand on it just as you do now.

This process is similar to some forms of meditation where you learn to let your thoughts go wild without you. You may want to reference this sort of meditation if you end up having troubles or are curious about the topic.

An important step in the ability to listen to your tulpa is the ability to prime your thoughts. Doing this involves being able to intentionally reproduce the state of mind you enter after you address your tulpa but before you get a response. As you become more and more practiced at normal communication with your tulpa, your familiarity with this state of mind and your ability to reproduce it should increase. Your end goal is to be able to get into this state of mind without asking a question or addressing your tulpa, and to be able to hold onto that state of mind for a long duration of time, or at least a minute or two.

To start the process of hearing your tulpa think, you should seek a neutral space with a good number of things that can be observed or thought about. This could be a quiet living room filled with various decorations, or your bedroom at a peaceful time of day. Optimally, you want to be in some sort of situation in which there are lots of little things around from which your mind can think things like, "Wow this room is nice". While these things are not strictly necessary, the more opportunity for idle thought on the part of your mind, the better.

To really begin, try to step back from your thoughts. Unfocus your eyes, stare at a boring wall or rest your head back, and try not to direct or control what you are thinking. After a moment of silence, you'll likely notice the ever-running engine of thought ticking away in the background. Topics tend to be left incomplete, and you'll find yourself picking and prodding at seemingly random sources to think thoughts about. It could be the details of the boring wall you are looking at, or something that happened through the day, or your opinions on this very guide. Whatever it is, once this idle thought engine is running without your active input, you should have a good sense of what it means to step back from your thoughts.

Finally, attempt to do the above while priming your mind to think under the scope of your tulpa. Focus on them as you step back from your thoughts, and if you are lucky those idle thoughts which were once yours will start to either bounce back between your own sense of self and your tulpa, or hold steady in their new voice and cadence. Early on, you'll likely notice that you have a tendency to respond to your tulpa during this time, especially to serve as a way to compare and contrast your own thoughts with the primed thoughts that fall under your tulpa. Don't try too hard to supress this, just go with the flow and encourage your mind to speak as your tulpa wherever possible.

Once your mind is primed to think as your tulpa you can start to look around the room you are in and focus on various objects which your tulpa may find interesting to comment on. As these thoughts come in, your aim is to observe that thought without commenting on it. You should be able to keep on priming your mind and start listening for the next thought. If you are lucky, you should see your mind thinking further thoughts under your tulpa, leading to your tulpa carrying on a narrative of thought without your intervention.

As a very crude case study, imagine a tulpa whose main personality traits so far can be outlined as such:

They grew up in a place where everyone was expected to sacrifice themselves for their community.

They've been at odds with nature for a very long time, and wherever they lived has had a ton of flooding.

Consider a situation in which your tulpa somehow ended up on the topic "Why are people arguing against building a flood wall on the river?".

Rather than asking your tulpa what they think of these people, and getting a "That's selfish" response a moment later, you may notice something akin to the following while listening to your tulpa:

"A person should always put the community above themselves." ... "The flood wall would help a ton of people" ... "What happens if it floods and people die?"

Note that these responses aren't addressed to you, and are instead formatted in first person like your own thoughts when you consider a topic. This sort of running narrative is what you are looking to generate by learning to put yourself in the listening state of mind.

As time passes, you should be able to apply this listening technique to questions, or when you are going about your day doing something mundane like shopping. With time and practice, it may well be possible to have this sort of listening state be a more common engine for your tulpa to produce thoughts than the earlier gap-fill engine taught in this guide.

If all else fails, simply try to listen to your tulpa speak. Sometimes just doing what feels natural to you can be far more effective than any amount of advice that could be given here.
