Of course, there must also be faith in the holy name and in the order of the spiritual master. We must have faith that by both chanting the holy names and executing the instructions of the spiritual master, our lives will improve, and we will become more peaceful. That faith comes from taking the association of devotees who manifest these qualities, and by seeing how they characterize the qualities that you are wanting to develop. By serving such devotees, you will also develop their qualities.
