Non-dualistic truth is supreme truth; all dualistic systems hold false self [ego] as real self and false experience [universe or waking] as reality

Non-dualistic truth is supreme truth; all dualistic systems hold false self (ego) as real self and false experience [universe or waking] as reality.  Non- dualistic wisdom is culmination of all systems including theistic non-duality.   The true non-dualists will not quarrel and argue with any theoretical philosophy because he is fully aware of the fact that, this orthodox theistic non-dualistic scholars or pundits like Dualists sages could not distinguish between ‘I’ and ‘formless witness.’ The 'I' was the witness. Their highest was the Jiva. One is so much attached to the 'I' that he do not want to think that 'I' does not exist. Again one is unable to detach the ‘I’ from the Real witness.

There is need to study the scriptures. One has to self-search the truth and realize it without the scriptures. And then when he reads the scriptures he becomes aware the scriptures are also saying the same thing but everything is misinterpreted.   Non-dualistic truth is supreme truth; all dualistic systems hold false self [ego] as real self and false experience (universe or waking) as reality. 

Man and his experience of the world is product of ignorance. Ignorance is cause of experiencing the duality as reality.  The duality is mere illusion from ultimate standpoint.  All the thoughts, words,   feelings, attachment including the man and his experience of the world are part of the illusion. The illusion (universe) is created out of single stuff. That single stuff is consciousness (soul or Atman), the innermost self.    On the standpoint of the soul, the innermost self no second thing exists other than consciousness.
