Intellectuals may say the external world is a construction of the mind. Deeper self-search reveals the fact that, causal relation is never found between the subject and the object, and then there is no sense in intellectuals claim, which is based on false self (ego or waking entity) within the false experience.
The waking or dream is not mere egoistic imaginations, but they are appearances. This must be understood. In dream the most important thing is that it has appeared spontaneously, in dream the dream entity may be a minister or a doctor, or a peasant, and it is not imagined or constructed by the waking entity. It is not the idea of the waking entity, which is present only in waking experience, but the soul, the innermost self, which is fully aware of the three states, which comes and goes in succession.
One may have seen the birth and death of other beings within the waking or dream, but one has never seen the birth and death of the knower or the seer or the witness of the three states.
One may imagine it but even that is possible within the waking or dream. In other words the formless witness of the three states must be there before their appearance. Hence the witness which is the true self, is termed "the unborn, because it is formless.
One has never seen the formless witness going, so one cannot call it mortal, because it is ever present in all the three states. It can remain with or without the experience of duality.
The three states (object) must be of the same stuff as the witness (subject) of them because they disappear into the soul or the self or the witness.
Knowledge derived from wisdom or Gnana is content less existence, whereas intellectuality is the ordinary dualistic knowledge. Intellectuals have no idea of the first definition of it as yet because they are not aware of the existence of the formless witness of the three states. And they refuse accept anything other than their accepted truth which are based on the false self (ego) within the false experience (waking). "Intellectuality” is a nothing to do with Brahmic – Gnana or non-dualistic wisdom. Intellectuality is useful in practical life within the practical world. And its judgment is based on logical conclusions based on the ego which is not the self.
Many intellectuals have a tremendous intellect; most will agree with their theories based on the ego, which is false self within the false experience. It does mean possesses Self –knowledge or non-dualistic Gnana? And knowledge based on the false self within the false experience is limited to false experience (waking) therefore it is certainly not self-knowledge.
Gnana is usually translated as "knowledge" but that is because there is no equivalent word in English. It is more accurately "content less consciousness" or “self-awareness”.
Most think awareness usually implies something, thoughts or things, but it is the formless non-dual nature of the Atman or the soul.
