Truth began to explain the subject of Transformation. This confused Error to such an extent that he changed the subject and suggested that they go for a swim. Truth took off his beautiful robe and jumped into the water. Deceitful Error grabbed Truth's robe, put it on and ran away wearing the beautiful robe of Truth. When Truth discovered that Error had fled wearing his beautiful robe, he decided that Error's treachery must be exposed.
Truth needs no cover of any sort.
Truth knew that he had nothing to conceal or hide and is perfectly willing to be looked upon as he is. This is not so with Error. He knows that, to be accepted, he must at least be partially covered with the Robe of Truth. Nowhere in all the world has he been so readily accepted as in the realm of religion. Error continues to wear Truth's robe.
