People think that religious Aachaaras are all merely external. The truth is that external activity and symbols also do good internally. The activity performed by the body and the disposition ( Bhava ) have mental relationship.

Someone hears most unexpectedly that he has won a huge lottery. Immediately his happiness is unbounded. This is only a mental feeling. But because of his mental feeling there is palpitation, breathing is affected and he may become unconscious. Those who question this relationship between the external symbols and the internal may think, whether the man in army will not get courage if he is not in uniform. But, all over the world the military man has a uniform. It is also said that this uniform itself induces courage
