The mind is the principal cause of bondage and the same mind also could become the cause of our moksha, liberation. So this mind factor is a very meagere factor in our lives. In fact, we are governed by the mind’s dictations, knowingly or unknowingly we will follow them all the time.
Mind could be your enemy or your friend. So during chanting we want our mind to be our friend for always. That is the goal. During chanting we have to strive harder to make our mind our friend, so it doesn’t go against us and drag us here and there.
