1. Radha-Krsna pastimes can only be understood by elevated devotees

    In His spiritual form, Krsna enjoys His spiritual energy, and that is the sum and substance of the Radha-Krsna pastimes. These pastimes can only be understood by elevated devotees. One should not try to understand the Radha-Krsna potencies and pastimes from the mundane platform.

    Generally people misunderstand these as being material.
