When an iron rod is put into a blazing fire, the rod soon takes on the qualities of the fire; namely light and heat. But if the same rod is put amidst some ice, then it will remain simply dark and cold. In the same way, a devotee should associate with fellow devotees, and in relationship to others the devotee should try to elevate them also onto the spiritual platform. So please follow this principle and surely you will mark great strides in the matter of your spiritual advancement.
