Chidakasha is the metaphysical concept of an infinite realm that is luminous, all-pervading, innately sentient, and full of pure awareness.
Hindu texts describe it as both the foundation and enduring essence behind all perceived reality, unaffected by the transient nature of physical forms.
Chidākāsha is the result of Divine Ideation which makes the world a mental projection that functions within time and space to give itself a semblance of reality.
[5] Chidākāsha also means the space of consciousness and the space behind the forehead which is the seat of visualization that links man with the conscious, subconscious and super-conscious and also the object of meditation or ishta deva; it helps gain insight into the connection between the two confronting worlds – the higher that is beyond all objects and thought and the lower which is the material world of senses.
He states:- Then all wrong identifications and knowledge of the anatman cease to survive, there is complete removal of sorrow, and all that remains is the Infinite.
