All reality has its source in Brahman. All reality has its grounding sustenance in Brahman. It is in Brahman that all reality has its ultimate repose. Vedas specifically, is consciously and exclusively aiming toward this reality termed Brahman.
When the soul, the innermost self stabilizes in its own awareness, then it will transcend the illusory ‘I’ and reveals its formless,timeless and spaceless true nature.: ~ Santthosh Kumaar
The seekers aim is the search for the Ultimate Truth or Brahman, the search to find the non-dualistic truth that in actuality never was lost, only hidden.
As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent truth of the soul, the innermost self, which is hidden by illusion and its effects, is to be attained through self-knowledge followed by reflection, and so forth, but not through perverted arguments.
Therefore, the seekers of truth have to personally strive by all the means in their power to be free from the bondage of the illusory experience of birth,life,death and the world (duality).
Thus, one has to know what is real by realizing our body and our experience of the world is mere illusion created out of the soul or consciousness. The soul is the innermost self. The nature of the soul, the innermost self is emptiness. And it is identified by different masters with a different name, such as God or Brahman or Self or God.
The soul, the innermost self is beyond the form, time and the space. The soul is present in the form of the spirit (consciousness) . The form, time and the space are created out of a single stuff. And that single stuff is the soul or the spirit. The knowledge of the single stuff is the self-knowledge or Brahma Gnana or Atma Gnana. The Formless Path is a path to realizing the fact that, the self is not the form (mind) but formless soul.
Thus, the self-knowledge makes one realize the soul or the spirit alone is real and the form,time and the space are mere an illusion.
The soul (spirit) is self-evident. It is not established by extraneous proofs. It is not possible to deny the soul, because it is the very essence of the one who denies it. The soul is the basis of all kinds of knowledge, presuppositions and proofs. The soul is the innermost self. The soul is within, the soul is without; the soul is before, the soul is behind; the soul is on the right, the soul is on the left; the soul is above and the soul is below. Until one thinks his body as the body, ego as the ego the universe as the universe, he remains in ignorance, because he is still in ignorance and he is unaware of the fact that, they too are the soul,which is present in the form of spirit.
