Original sentence: AOLF has also been made unsubstantiated claims about the effectiveness of Sudarshan Kriya in treating patients suffering from not only depression and trauma but also cancer and AIDS.At that occasion AOLF took out a full page ad in the New York Times, advertising its free offering of educational courses.Critics also complain that some AOLF followers  are quick to savage anyone who questions the organization's teachings or the commercial nature of its practices.Critics charge that such claims are at best exaggerated and misleading, and at worst dangerous.Followers also point out that AOLF courses are sometimes taught for free, especially in prisons, and most prominently after the September, 11, 2001,  attacks in New York.In an interview Sri Sri Ravishankar also expressed discomfort with his followers touching his feet and  showering him with flowers - however the practice continues.Notably, even some AOLF volunteers have objected to such conduct saying that it goes against the teachings of the organization.Only anecdotal data and personal testimonials have been provided to back up these claims, and no studies in internationally recognized scientific journals have been published.Others critics have highlighted that breathing practices including hyperventilation and active breathing have existed for a long time both in Western countries and especially as part of Yoga in India; and charged that Sudarshan Kriya is simply a new marketing term for old exercises.Otherwise, it would have become a commercial commodity in the US long ago.Sri Sri Ravishankar has also been accused of leading a personality cult, with followers and volunteers treating him as a deity; construction of a grand Ashram in Bangalore, India; and ostentatious celebrations of the Silver Jubilee of Sri Sri Ravishankar's enlightenment.Sri Sri Ravishankar has defended AOLF's actions by stating that the Sudarshan Kriya was patented, "Because someone else was going to patent it.Sri Sri Ravishankar has rejected such claims saying that Sudarshan Kriya is different and one has to experience it for oneself in order to appreciate it.The AOLF has faced criticism for the high fees it charges for it courses and the non-disclosure forms it makes participants sign.These practices seem to go against its stated goals, as does its claim of having patented Sudarshan Kriya (although there is no evidence to support this claim).We patented it so we could teach
