Let the mind wander as it likes. Name is necessary to concentrate the mind. What is the use of breaking a trained horse? But one has to adopt various stratagems to bring an untrained horse under control. The object of worship is just to bring the mind under control.
When one starts taking the Name, the mind like a horse tries to wander about. Pay no attention to it but cling tighter to the Name of the Lord.
You will find that your mind and speech would have come under your control within a short time.
Do not forget the Divine Name on any account and do not listen to others in this regard.
