Verse 97

97. If there is difference even of the measure of an atom, being produced, for an unwise one, there is not always the state of being without attachment; much more therefore there is no slipping away of the veil covering the Highest.

In Unity, Advaita, there can be no difference. Because "I" Alone Exist there can be no difference. Difference means more than one, duality.
The being covered by ignorance that sees duality cannot avoid attachment, fear and desire. This is because if in truth there were many true existences each existence, each person, would feel incomplete. There would always be something else that needs to be desired to enhance each individual to maintain stature with "others". This leads to ambition competition and fear.
The person that even suspects there is something he has not got will always be at the risk of the evils that arise from ignorance of duality. Those who have Realised the Unity of The Absolute Self Alone are free from the evils of duality.
