When a point is centred it is stable. The mind is at rest. When it is off centred things change....
A point cannot be measured, it has no length, width or height.
It has no movement.
When it is placed with other things to compare, and is off centre
there is a different dynamic occurring. The brain wants to 'even' up the area in some way
A small round window in the corner of a wall or a painting off centre, will draw attention to one side of the environment.
