How does one get the knowledge? What is meant for knowledge? What is true knowledge? –all this of which must be dealt with the seeker of truth in order to realize thee ultimate truth.
The self-knowledge does not destroy the world but it exposes the unreal nature of the world which appears as waking and experienced as reality by the person within the waking. Same way the unreality of the dream was exposed when waking took place.
People talk of liberation. They are only forming an idea. Idea is mere imagination; imagination is possible only in ignorance. People, who are so confused as to be unable mentally separate the formless witness from the three states, speak of gaining liberation. But all such ideas are only possible in waking experience which come and go, the formless witness or soul needs no liberation.
The destruction of the world and man within the world does not mean that they should become imperceptible to the senses but there should arise a determination of their unreal nature; for if that were not the case, people may find emancipation without any effort on their part as during dreamless sleep and fainting.
That consciousness remains as the sole real factor, means that there should be a realization of ultimate truth or Brahman as the sole unity and not a mere absence of the cognition of the world; otherwise there would be no such thing as emancipation in this very life not in next world and next life
Emancipation can occur without yoga. What can be done by yoga can be done by Gnana. Yoga alone leads to Samadhi, but Gnana also liberates self from experiencing the illusion as reality.
If it is said that one get Gnana in Samadhi in which there is no duality, it is no better than sleep. If it be said that there is a direct cognition in profound contemplation in which there is no difference between the perceiver and the perceived and in which no duality can occur; then why not admit the same in deep slumber. If it be objected that there is no knowledge of the nature of consciousness, which is the innermost self in deep sleep, then one admits that self-knowledge only is true knowledge and not the absence of duality.
That consciousness remains as the sole real factor, means that there should be realization of consciousness, which is ultimate truth or Brahman as the sole entity and not a not a mere absence of the cognition of the universe; otherwise there would be no such thing as emancipation in this life.
Those people, who talk of experiencing the ultimate reality, do not know that the word experience implies something else, a second to be experienced, i.e. duality, i.e. non-reality, and those who talk of "direct knowledge" of reality again do not perceive that knowledge implies a second thing to be known; i.e. duality exists. i.e. no reality in waking experience. To know the ultimate reality means to know the complete negating of all that is not this reality. Hence one does not make an object of it.
