To whom it may concern:
Dahn "yoga" is a belief system based largely upon devotion to its "Grand Master" Lee.
Much like Rev. Moon of the Unification Church, Lee sees himself as something of a messiah and claims that he can channel energy supernaturally to his followers.
Dahn masters devote their lives to Lee, often working for little pay, no benefits (health insurance, 401 K). Many of the so-called "little masters" are from Korea.
The Ross Institute has received many complaints about Dahn, including complaints of physical injuries, complaints from unhappy former staff and people that felt Dahn financially exploited them through high pressure sales tactics.
There is currently a wrongful death lawsuit filed against Dahn by the family of a woman that died while attending its retreat in Sedona.
Dahn has often been called a "cult" and accused of using "brainwashing" techniques to manipulate its adherents.
