Ashtanga yoga literally means "eight-limbed yoga," as outlined by the sage Patanjali in the Yoga Sutras. According to Patanjali, the path of internal purification for revealing the Universal Self consists of the following eight spiritual practices:
Yama [moral codes]
Niyama [self-purification and study]
Asana [posture]
Pranayama [breath control]
Pratyahara [sense control]
Dharana [concentration]
Dhyana [meditation]
Samadhi [absorption into the Universal] (Scott 14-17)
I define religion as what you practice that deals with your soul/spirit. This would be EXACTLY like someone saying that a Baptist church funding a prayer session is not religious because they didn't have anything religious in the class. Even though prayer has been around a long time before organized religion and is often seen as secular (wishes/karma/blahblahblah), if a Baptist preacher is teaching a prayer session, they are being religous. JUST like a guru teaching Ashtanga yoga is being religious (or spiritual) when they are practicing it.
As for the Jois family not being religious, you guys must not have clicked on any of the biographies listed. All of them are gurus or learned from a guru and the woman teaches in temples and the word spiritual pops up quite a bit. Do you separate the term spiritual from religious? I know you can be spiritual wihtout being religous, but the fact that there are leaders, teahcers, and an outline for their followers to use, means it's a religion whether you want to acknowledge it or not.
the rest of it was blocked from work and I do have some to do, so I'll post the rest later.
