That which is unreal, that is duality, cannot contradict truth, non-duality. It cannot be counted as an adversary of non-duality. The
illusion cannot, 'oppose' the substratum, reality. It can at best lead to
the mistaking of the substratum. Perfect understanding is the only way to
overcome the ignorance.
Non-duality is the ultimate undeniable Truth.
Realization presupposes a state where there is ignorance about that
Truth. That such is not the reality is evidenced by the possibility of transcending the ignorance. When this is achieved it would be clear, that
all the three states are mere mirage created out of consciousness. The one
which is aware of these three states, which comes and goes is neither waking
entity nor dream entity. It is the
consciousness, which is within the three states and also it is without the
three states.
Self- Knowledge or Brahma Gnana or Atma Gnana is only is true knowledge not the absence of
duality. Self -Knowledge or Brahma Gnana or Atma Gnana cannot destroy
the world but it eliminates the ignorance and exposes the unreal nature of the
mind or universe.
Non dual wisdom requires
investigate in to the mind, analyzing the mind, which appears as universe,
realizing the fact that, the mind rises and subsides from formless source,
which is soul or consciousness. The
consciousness is the innermost self. Therefore, one has to learn to view and judge the truth
from the standpoint of the source from where the mind rises and subsides, not
from the standpoint of the waking entity, which is the false self within the false experience.
As one gets convinced, certain, of the truth that the world is
nothing but consciousness, and there is no second thing, then he get conviction
that, all the three states to be consciousness in the midst of duality. Realizing the truth in the midst of duality
is wisdom.
