I don't know about The 3HO gurdwara in New Mexico but the ones I've been to here in Mexico always have the photo of YB. One time they even projected a video of YB above the S.G.G.S. I was annoyed in the extreme.

One of the other major problems I have is that they promote superstitious beliefs ie. the age of aquarius, numerology, repeating mantras (stolen from the S.G.G.S.)for specific results, prosperity, health etc.

One of the the things that attracted me to Sikhi in the first place was the rejection of supestition,astrology,etc. Here in Mexico superstitious beliefs are rampant. My Wife had a friend from College whose father was/is a Brujo(witch).He was able to buy a new car every year and send his kid to college. Nice work if you can get it I guess. My point is that these superstious trappings really send the wrong message to people who are already susceptible.
My wife and I are trying to inform people about Sikhi by having Gurdwara about once a month. We're learning Gurmat Sangeet. We've published pamphlets in spanish that we downloaded from Sikh Coalition.
The message of the Gurus is really needed here (everywhere that is) so we want people to find it without a lot of unnecessary additions. That's where the problem of 3HO comes in. One time, I invited someone who was famliar with kundalini yoga to gurdwara and she asked "what are the benefits". I think she was waiting for me to say it will open your third eye or something. When I told her it was about listening to kirtan and explained that it was the teaching of the Gurus in musical form and about reading from the S.G.G.S. etc. She was disappointed. Again she asked "so it doesn't have any specific effects. I told her that it could possibly make her a better person If she did it enough but she wasn't impressed and didn't show up.
I think they give the wrong image of what Sikhi is, so trying to work against that is tough. I guess no one ever told me it would be easy either
