This class is just mentioned in order to make the catalogue complete,
but it is of course very rarely indeed that so exalted a being
manifests himself upon so low a plane as this. When for any reason
connected with his sublime work he found it desirable to do so, he
would probably create a temporary astral body for the purpose, just as
the Adept in the Mâyâvirûpa would do, since the more refined vesture
would be invisible to astral sight. Further information about the
position and work of the Nirmânakâyas may be found in Madame
Blavatsky's _Theosophical Glossary_ and _The Voice of the Silence_.
