" I and the Father are One "....

"I and the Father are One," said Jesus. The student asks why the
individual should not therefore know the One as oneself? The saying of
Jesus presuppposes duality and difference, which explains why the
awareness such a student seeks does not exist; it can come only after
all duality disappears--even that mystical monism which seems to have
transcended duality but has not really. The theosophy of The Secret
Doctrine does not reach the height of the doctrine of Nonduality. That
is quite all right because it purported to be only a "fragment" of the
truth. H.P.Blavatsky wrote that the Causeless Cause, as she termed it,
the Absolute, was unknowable and that seekers could reach only to the
Logos. Dr. Brunton does not teach that. If all else but the Absolute
is illusory (including the Logos) then the path is not worthwhile
because truth is unattainable. This philosophy says that Truth is
attainable and the so-called Absolute can be realized by man. Some
theosophic studies will help in the understanding of the teachings of
this path, while others will bring the student's mind into direct
conflict with them. He will have to decide for himself whether to give
his loyalty to the one or the other, but this doctrine cannot be mixed
with any other save at the risk of diluting its truth. This path is
based solely on the appeal to reason, never to belief, whereas there
are many items of theosophy which no one can prove.
