The Michael Teachings

Is this 'Michael' the same 'Michael' as the Archangel Michael
 that several people claim to channel, write books about, etc..?

No, this Michael originated in the San Francisco Bay area of California in
1973, and the material was later published by author, Chelsea Quinn Yarbro.
There is no relation at all to the Archangel Michael.
