At the time when the last chapters of "The Synthesis of Yoga"
were written in the Arya [ = 1920-1921], the name "Overmind"
had not been found, so there is no mention of it. What is described in those chapters is the action of the Supermind
when it descends into the Overmind plane and takes up the Overmind workings
and transforms them.
The highest Supermind or Divine Gnosis existent in itself, is something
that lies beyond still and quite above.
It was intended in latter chapters to show how difficult even this was
and how many levels there were between the human mind and Supermind and
how even Supermind descending could get mixed with the lower action and
turned into something that was less than the true Truth.
But these latter chapters were not written.

"The Synthesis of Yoga" was not meant to give a method for all
Each side of the Yoga was dealt with separately with all its possibilities,
and an indication as to how they meet so that one starting from Knowledge
could realise Karma and Bhakti also and so with each path. It was intended when the Self-Perfection was finished, to suggest a
way in which ALL could be combined, but this was never written.
