Why the statues are made of five metals (Pancha Loha)?

A statue is a model representing a concept. It is actually a teaching aid of the spiritual preacher who can be Lord Datta alone. Datta means the Lord given to the world in human form. The human body of the Lord is made of five elements (Pancha Bhutas). The statue is in human form which represents the human body of the Lord. The five metals represent the five elements. This means that the body of the Lord is also the same Prakriti [part of material nature]. Therefore the body of the Lord will have the qualities of Prakriti like hunger, thirst etc. Prakriti is the shirt of the soul or the Lord. A blade can cut the shirt of any human being. Similarly the blade can cut the shirt of even a king. This means that you should concentrate on the inner form of the Lord which pervades all over the human body of the incarnation just like the electric current pervades all over the metallic wire. The wire gives you an electric shock, which is the property of the current. But the wire also maintains its own property like leanness etc.

Similarly the human body of the human incarnation has the property of the inner form and also its own natural property. Therefore you should recognize this truth and worship the Lord in human form by offering food etc. You should not think that since He is the Lord, that He would not have hunger. Of course the Lord can use His divine power to remove His hunger. The Lord does not use any divine power for the sake of His human body. The very purpose of the human body of the Lord is to suffer the results of the sins of His devotees. In such suffering, the human body must follow the nature of Prakriti and must suffer like any other human being. If the Lord uses His superpower to remove or reduce the suffering, the deity of justice is cheated. Thus the statue represents the human body, which consists of five elements represented by the five metals of the statue.
