The Supreme Self, the Godhead in you, is enveloped, obscured by innumerable desires. Spiritual disciplines have been prescribed from time immemorial to eliminate desires and reach the ultimate Goal.
When a person gains the knowledge of the Self, he becomes liberated from all desires.
The pursuit of happiness would not cease until you reach your original being of peace and bliss.
To get yourself free from desires and gain absolute libration you must return to your original State, attain Self-Realisation.
As long as the mind contains unfulfilled desires it will remain agitated, frustrated, stressed out. Hence religion has personified desire as the devil obstructing the divinity in human beings.
