"After giving a summary of the beauty of Krishna, Ramananda Raya began to speak of the spiritual energy of Krishna, which is headed by Srimati Radharani. Krishna has immense energetic expansions. Three energies are predominant: the internal energy, external energy and marginal energy. This is confirmed in the Sixth Chapter of Vishnu Purana where it is said that Vishnu has one energy, which is called spiritual energy, and it is manifested in three ways. When spiritual energy is overwhelmed by ignorance, it is called marginal energy. As far as spiritual energy itself is concerned, it is exhibited in three forms because Krishna is a combination of eternity, bliss and knowledge. As far as His bliss is concerned, His spiritual energy is manifested as the pleasure giving potency. His eternity is manifested as energy, and His knowledge is manifested as spiritual perfection. As confirmed in Vishnu Purana (1.12.69): 'The pleasure potency of Krishna gives Krishna transcendental pleasure and bliss.' Thus when Krishna wants to enjoy pleasure, He exhibits His own spiritual potency known as hladini.
"In His spiritual form, Krishna enjoys His spiritual energy, and that is the sum and substance of the Radha-Krishna pastimes. These pastimes can only be understood by elevated devotees. One should not try to understand the Radha-Krishna potencies and pastimes from the mundane platform. Generally people misunderstand these as being material."
