Attachment to objects causes an illusionary division between the subject and the object (the observer and the observed), so the illusion of psychological time.

Psychological suffering (fear, sorrow, desire, despair) is caused by the illusive fragmentation caused by thought.

This mechanism is one of the characteristics of the fragmentary perception of thought.

The epistemological definition of Unitary Perception is: observation encompassing the observer and the observed at the same time.

Unitary Perception is freedom from illusion.
