The union of tulpa and tulpamancer working in tandem to realize a desired task or goal. This is achievable with most mature tulpas. This can be further enhanced by the clarity and the intensity of the tulpamancer's concentration level. At this processing wavelength, both tulpa and the tulpamancer are one.
The term "parallel processing" is also often used to refer to the host and tulpa maintaining fully separate, concurrent cognitive processes. Many mature tulpas appear capable of this, but whether true parallel processing is possible has yet to be proven.
