Pranayama Everywhere

I was browsing through the quarterly health newsletter that I receive as a benefit from my health insurance and I found an interesting piece in the stress less colum.  The piece, entitled A calming breath, gave a very brief description of anuloma viloma pranayama.  Unfortunately, the piece gave no source information nor does the piece mention Yoga in any way.  While it is great to see Yoga spreading, I find it unfortunate that it is spreading in such a clandestine manner.  At some point the fact that the breathing technique described is a commonly practiced pranayama techinique is being hidden.  Surely this article will benefit someone but what greater benefits could it have carried had it mentioned that this is a breathing techinique commonly used in Yoga?
