A leader can help others if he can always see the good in them. A preacher will think, “If somebody needs to develop good qualities, then as a preacher, I am partially responsible if that person does not have those qualities. The person will not improve unless he has the association of somebody who can help him and who cares about him.” Thus, devotees can help each other by seeing the good qualities in each other. By so doing, we can encourage them so that they will feel sheltered, and will then automatically want to come up to a higher standard. Such are Vaishnava relatonships.
