Is lust a real entity that exists separte from us or is it just our own misdirected desire?

From Praveen (Main questions from a long interactive QA session) :

1. Does lust originate in the mind or in the soul?

2. If lust is a standard form of distortion of our original desire to love Krishna, then why is it not expressed in children and expressed differently in males and females?

3. Are anarthas fundamental unchangeable programs given to us by nature or additional changeable impressions created by us?
