Blank vote (leaning toward disapproval, if can't opt out of this vote), Tips and Tricks.
The tip is mostly fine, although I question its usefulness:
I had asked my tulpa to do something similar, long before this guide was written, and it sort of "worked", but it didn't really make me trust that the answer really came from my tulpa. What worked instead? The tulpa learning to communicate emotionally and having that person "essence" feeling - if a thought was theirs, you would end up implicitly knowing it came from them and it would usually be surprising as it wouldn't feel caused by you - it would feel as if the thought is theirs, no matter how simple or complex the thought was.
