The three states which is an object to the formless witness (the soul, the innermost self) is ever-changing but never the formless witness.

The three states which is an object to the formless witness (the soul, the innermost self) is ever-changing but never the formless witness. The three states come and go, but that does not prove that one state produces or causes another. 

If the previous state of consciousness has really vanished, the memory of it would be impossible. Its disappearance into the source or soul is no real disappearance. One only remembers that it has gone and come; that which perceives these states can alone be said to exist: That is the soul, the innermost self. One only relies on the formless witness or soul, and none has seen the birth or change of formless witness or soul. –FORMLESS PATH
