Freedom is touching God with pure love. To touch the world is attachment.

Do not think that it is wasteful to imagine. You aspire for your son or daughter to become a doctor or engineer. Being a worldly aspiration it may or may not be fulfilled. But if you aspire for God and keep your imagination centered on Him, it will surely come true. Initially, I used my imagination and today it has become reality. There is a special happiness in imagining about God.
