OK, I’m starting to understand @cak and @Judi. My teachers don’t get into the spiritual stuff much. When they say anything, it is always qualified as generic, or they even qualify it in a way that I think most atheists would approve of. Also, depending on the studio at which they’re teaching that day, they may or may not do any chanting (OM, etc.); usually they do not.
It’s funny because their main teacher, Rusty Wells, teaches Bhakti yoga which by definition is heavily spiritual. His classes involve a lot of chanting at the beginning and end, but before going into it, he qualifies it. He explains that it is spirituality and not religion and explains the differences for those who do not know. He explains the meaning behind the Sanskrit phrases and makes them non-threatening to people of various religions or those without faith. I am spiritual, but not religious (though I was raised Catholic). My Catholic upbringing always tweaks my head when I hear any chanting, but I can go with it now. I think finding the right teacher is a big part of anything. I’m lucky to have such an abundance here.
