"Swami Vivekananda Saraswati" AKA Narcis Tarcau a Romanian man is the founder of Agama Yoga and would be thrown in Jail if he were running his "retreat" in any developed country.  A little searching on google can bring up many reports of people who have been coerced into having sex with him at his so called tantric retreats.

Each participant is "strongly encouraged" (bullied) to have unprotected sex with at least 5 others.  As you can imagine the prevalence of sexually transmitted diseases is incredibly high here. 

"Swami" has his first choice of women and the remaining men and women then choose their partners.  Like many brainwashing groups Agama has a lot of beneficial practices however the harmful practices far outweigh any of the benefits.  Similarly, "Swami" speaks a good game and perhaps 80% of what he says sounds good and right however the remaining 20% is manipulative, cunning and exploitative. 

Steer clear of Agama Yoga.
