The believers, and particularly those who have not had sufficient experience in teaching, should be very careful in the way they present the teachings of the Cause. Sincerity, devotion and faith are not the sole conditions of successful teaching. Tactfulness, extreme caution and wisdom are equally important. We should not be in a hurry when we announce the message to the public and we should be careful to present the teachings in their entirety and not to alter them for the sake of others.
