Premanand Maharaj Ji
Why is moh called a delusion, and how is it different from love for Bhagwan?
Moh is the delusion of 'mine'
Moh is the avidya (ignorance) created by maya, the belief that this is my wife or my son. Feeling for Bhagwan is anuraag, not moh.
What is felt for Bhagwan is called anuraag and prem, and what is felt for people, things and places of the world is called kaam, raag, moh and aasakti.
