A Pure Void.

When consciousness is without movement, that is the all-embracing fullness of Reality. Inasmuch as there is movement in consciousness, that Reality appears false. This is like the opening and closing of the eye.
As an illustration of this,
observe the manner in which
there is wind when the air moves, and
when it is still, there is not.

– Ozhivil Odukkam. Verse (47)
By Sri Kannudaiya Vallalar

Commentary by S. Ram Mohan
and Robert Butler.

Mind is nothing other than the arising of movement in consciousness.
The importance of stilling such movement within consciousness is underlined in Sri Ramana’s translation of Devikalottaram v. 10:
“When the mind moves even a little,
that is samsara.
When the mind abides firmly and motionlessly (in the state of the Self),
that is mukti.
This is certain.
Therefore know that the wise man must hold his mind firm by supreme Self-Awareness.”

The word puranam, Sanskrit purna, means fullness; it is used here to indicate the absolute Reality, that which embraces all that is or ever could be, the source of the infinite potential of creation.
Later, in v. 90, the Self will be characterised a verum pazh – a pure void. The Self subsumes equally the all-embracing fullness of manifestation, as in the waking state, and the pure void of the unmanifest, as in deep sleep, yet is beyond both.
This Reality appears false to the extent that the mind-based personal consciousness convinces us that it is itself the Reality.
The ‘Real’ thus becomes just another mental construct which the mind perceives as exterior to itself, something to be sought after and gained.

When the eye closes the world picture ceases to appear in a person’s field of vision.
In a similar way, when the personal consciousness subsides into the universal consciousness of the Self, the entire world of names and forms no longer appears in the jnani’s consciousness.
