I don't think any of these people listed in those articles or by me would meet the DSM5 criteria for DID. However even if they did, it is beside the point. The point is that Tulpa's are real, first you questioned their existence, than you were too lazy to track down a study I casually mentioned, and than you doubted that Beyoncé and Bo Jackson have alter egos, though they both openly talk about having them, and then when I showed articles supporting my claims you became dismissive.
The bottom line is Tulpas are real.
They are used by a lot of people to gain success.
some of the people who use this esoteric knowledge do so openly, so there is no reason to doubt it.
