A sense of group belonging, and attachment to a projected ideal set of life circumstances...where "everything will be perfect"
Add to that the automatic sense of "instant friends" and love bombing...
Ask yourselves though, when was the last time a Normal, balanced, baggage-free person with no social issues came "into the truth"? Usually it is the disenfranchised, odd members of the community that are attracted to "the ring of the truth".
A well adjusted person rarely if ever comes into the "truth"
