"This most divine plane of the cosmos is named “The Pass Not Ring” in the first volume of The Secret Doctrine
by the Master Blavatsky. If we consider the cosmos as a great tree with
its roots in the Absolute, then these roots will be the “Pass Not Ring”
because no one can pass that plane, not even the greatest Gods of the
cosmos can pass beyond that ring." - Samael Aun Weor, The Revolution of Beelzebub
