Tulpa: A secondary train of thought you create through practice and training that has its own identity and its responses are autonomous and created subconsciously. Meaning the thoughts seem as if they were from another being and entirely unintentional from you. This is possible because basically you're associating a particular line of thought to something external and as the association gets deeper the process becomes automatic and you can keep making more associations to flesh out the identity of those thoughts more, which becomes a Tulpa.
