Is the only difference the hip levelling? And when both hips are to be level, that is dancer right? Standing bow is when the leg looks like it’s sprouting out of the top of your head?
Maybe Yoga Journal’s pose finder has some pictures that look like what you’re talking about. That’d help, I bet.
You’re asking about Natarajasana and what other pose?
^ I believe standing bow is Dandayamana Dhanurasana.
TIA!
Let’s see, how to say this tactfully.
The Bikram poses seem to be unique to Bikram.
It may thus be best to ask someone from that style of practice.
I do not know the origin of those poses, or “from when they came”.
