‘Nothing is form, and form is nothingness’ is a concession to the belief that there are things (Rupert Spira).
Then, there is the realisation that this belief, produced by consciousness, can be replaced by the realisation that colours, sounds etc are appearing out of consciousness.
Consciousness would not be be able to come up with colours, sounds, etc without employing thoughts, necessary to design the mechanics of perceiving colours, sounds etc.
Driving a car is most enjoyable without identifying with it or believing in it as a separate entity. However, the designers of the car had to invest a lot of thinking into the functioning of that car.
Realising the formless does not invalidate thinking as a tool to maintain the mechanics (vibrations) of perceiving colours and sounds for the sake of entertaining consciousness. Luckily, there is no need for consciousness to forget itself to perceive colours and sounds, but it has to forget itself as soon as it assumes beliefs in separation.
