For those who don’t know, a tulpa is an imaginary friend developed through a process called “forcing” (the act of focusing on and developing a tulpa’s presence or strength by devoting specific attention to them or otherwise interacting with them). In ancient times, tulpas were considered mythical creatures, but as our understanding of the world grew, people found a rational explanation for this phenomenon. After looking through guides on making tulpas, I found an uncanny resemblance between "forcing" and Christian prayer. You can watch any video on how to pray, replace "God" with "Rainbow Dash," and you'll essentially get a guide on how to make a tulpa. Through repeated prayer, a believer reinforces his delusions, which can manifest in the form of religious sensations and even voices in the head. So far, this seems to be the most logical explanation for why so many people felt that God was talking to them and were willing to die for their beliefs.
