An interesting publication looks to be Bindu, that comes out of Scandinavian Yoga and Meditation School. It says it has only a few of itsissues and articles online, but it does periodically change which issue is available. For instance, only issues Five, Eight and Eleven. I found, however, that by simply manually changing the address to another issue, you can see all back issues. Be forewarned, however, that English is not the native language of the writers so at times the prose can be a bit tortured. The seriousness of the publication makes up for any deficiencies. It puts a lot of emphasis on publishing scientific research into yoga, meditation and other disciplines.
