Formless Soul or consciousness is the foundation of whole physical existence.

 

 

The person, and his experience of the the world and his sense of form,time and space are made of single essence, which is formless consciousness. Until the diversity dominates the ignorance prevails. Until ignorance is there, the form,time and space prevails as reality. until the form,time and space prevails as reality , the experience of birth,life ,death and world experienced as reality. Until the birth,life,death and world is experienced as reality one remains in ignorance of the non-dual reality or Brahman. Thus perfect understanding is needed to realize what is what. thus seeker has to get rid of the mental  cobwebs  which is blocking his realization. All the cobwebs of  mental blockades  are because of the accumulated knowledge. thus careful analysis is required before accepting anything as truth.

The consciousness is the maker and the preserver of the mind, which is in the form of universe. Universe   appears as waking and dream and disappears as deep sleep. Formless Soul or consciousness  is the foundation of whole physical existence or universe.  thus the whole universe(form)  is dependent on the formless (soul) existence. thus the formless is the cause of the universe(form or mind)  and it itself is uncaused.

By knowing the fact that, the consciousness as the true self of which all three states becomes known? 

 

Two kinds of knowledge must be known. They are the spiritual Knowledge and the physical knowledge.   Of these two, the physical knowledge is of the worldly life.    And the spiritual  or Self - Knowledge  or Brahma Gnana or Atma Gnana  is that by which the ultimate truth is attained. 
 

By means of the Self- Knowledge, the Gnani behold everywhere consciousness, which otherwise cannot be seen or seized, which has no root or attributes, no eyes or ears, no hands or feet; which is eternal and omnipresent, all—pervading and extremely subtle; which is imperishable and the source of the mind, which appears as waking and dream and disappears as deep sleep.

 

As the spider sends forth and draws in its thread, as plants grow on the earth, as hair grows on the head and the body of a living man—so does mind, which is   in the form of  universe arise from the Imperishable consciousness.
