The objective of dhikr and of the dhikr that you have just done is if you like, a loosening up or a shaking off of our ideas of who we are, of our chains. It is about re-orientating oneself to the Lord, to Allah.
The natural order for the human being is disturbance and disquiet. The state of the heart outside of dhikr is one of agitation. It is with the dhikr of Allah that the heart becomes tranquil.
