The consciousness gives sentient to the insentient universe, which is in the form of mind.

The witness is, different from the witnessed that Consciousness is distinguished as not being the same; from the lifeless universe, which is in the form of the mind.   The lifeless universe has no real existence without the consciousness.  The consciousness gives sentient to the insentient universe, which is in the form of mind.  The universe exists as reality, when on the standpoint of the matter as self.

Man cannot live without the physical world; it is the basis of his life, so it must be the starting point of his inquiry. Things, not imaginations, must be the seekers material.

The one who knows ultimate truth or Brahman knows the world because uses his soul centric reason.

One who loses touch with the external world and gives himself over to his thoughts alone takes his illusions to be realities and remains in realm of perverted intellectualism.  Perverted intellectuality is nothing but egoic exhibition.

Both sides of experiences have to be inquired into--the duality [waking or dream or universe] and non-duality [deep sleep], i.e.  matter and spirit if one wants  to find truth of his true existence.

People avoid inquiry into the world, hence cannot find truth. If they think they do not see the world by shutting their eyes and omitting it from their thought, he is still a ignorant and not a Gnani. If there is nothing to be seen, if mere absence of the external world from cognition gave ultimate truth or Brahman, then every living creature would attain Gnana or wisdom because it loses the world in deep sleep.
