Varieties in the material world originate in real prototypes in the spiritual world
The reflection of the sun from a mirror is nothing but light within darkness. Thus although it is not exactly sunlight, without the sunlight the reflection would be impossible. Similarly, the varieties of this world would be impossible unless there were a real prototype in the spiritual world. The Mayavadi philosopher cannot understand this, but a real philosopher must be convinced that light is not possible at all without a background of sunlight. Thus the jugglery of words used by the Mayavadi philosopher to prove that this material world is false may amaze inexperienced children, but a man with full knowledge knows perfectly well that there cannot be any existence without Krishna. Therefore a Vaisnava insists on the platform of somehow or other accepting Krishna (tasmat kenapy upayena manah krsne nivesayet).
