Thank you to everyone for responding. Some responses back your way…
Hubert: I think you’re right in saying that I just wasn’t prepared for the chanting. The actual “doing” of it wasn’t what I was objecting to but rather, I was doing something sort of alien to me and with no real understanding of what it was all about and why we were doing it in the first place. I like your suggestion of NOT doing it and see what happens. I’ll try this way first, since that seems so “me.” Thank you.
But then, Tubeseeker: I also agree with your suggestion to ask the instructor more questions about chanting. I’ll try this way next because I DO want to understand more. Thanks for your advice. I also picked up on your “music soothes the savage beast” description. I chose the name “moth” partly because it’s the name of a song I like. And also because it’s a short and sweet word, and from nature, and close to “mother,” and I like the fact it’s a creature attracted to the light but lives in the dark. It’s also not a beautiful and graceful butterfly…
Hello and thanks for your welcome, Pandara: When you said, “watch your written/spoken/typed words,” I assume I said something I probably shouldn’t have said, or I said it too harshly? Please know that I thought carefully about each word, although words are tricky to me. I’m a painter and live in a more emotional, and I guess “abstract” state. Images don’t need to be as precise. And in some important way, this is the crux of my dark/light thing…I’m not sure I want to TOTALLY eliminate the dark energy because I feel I need it to create. But by holding onto any of it at all makes me wonder if that means yoga is not going to be a path for me. Well, I guess I’m here to find out.
And Mirjana: Yes, I will read the Yoga Sutras of Patanjali. I’m excited to find out what that is and was exactly the sort of specific direction I was looking for. I too, hope that I can make a clear and honest decision. I think I can do “honest” but “clear” seems to be the part in question. Thanks for your good wishes, too.

(this is just one side of the coin though …)
