I think Yawah was just a lie in order for Cygnus and other cult members to gain power.
Cygnus and other members of the cult are powerful psys. They purge other psys because they wouldn't want such a threat to stand against them.
Right after you defeat the bandits and a strange voice talks to you alone this could be evidence of a very powerful psy speaking to you over a great distance. A.K.A Cygnus.
Evidence to support the fact that The cult members are actually a bunch of powerful psy members is that [spoiler]if you choice to side with the cult during the "Raid the Armory" mission you get an end game message detailing your rise within the cult and the fact that they accept the fact you're a psy. I believe you even become very close with Cygnus.[/spoiler]
