Spiritualistic reason is not based on ego but the formless soul, which is the innermost self.

 

Reason should not be interpreted to mean intellect. Reason is that which finally distinguishes between real and unreal, false and true, and therefore it takes all the three states into account.

Till  that is attained people generally use only intellect which is confined to waking state only. Intellect evolves into Reason as man realizes that study of the waking world is not enough, and that study of all the phenomena of mind, consciousness is required. Such study must embrace dream and sleep; hence there is no perfection of reason without analyzing the three states of consciousness.

Reason literally means 'that which distinguishes the ultimate reality from the rest.' When such discrimination between truth and falsehood by the method of reasoning is confined to the physical plane, it is intellect, logic, but when extended to the spiritual plane it is reason.

Spiritualistic reason is not based on ego but the formless soul, which is the innermost self. Soul-centric Reason is that which enables one to distinguish the real from the unreal, true from false. The intellectuals do not clearly know the difference between intellect and reason.

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 Consciousness usually implies something, thoughts or things, but it is the formless non-dual nature of the Atman or the soul. 

The consciousness exists with or without the matter because without the consciousness the matter ceases to exist because the matter is created out of consciousness. It exists as matter in waking or dream.   And when wisdom dawns it is consciously aware of its formless non-dual true nature in the midst of matter, as in deep sleep.
