"Krishna has got also energy, the original purusa -- Radharani, energy, prakrti. Krishna is engladdened in the presence of Radharani. That is nature. Similarly, a man, he becomes energized if he has got a good wife or good mother. This is the history of the whole world. Any great man in this world, you will find that behind him he has got a good wife or good mother. Prakrti, energy. That energizes him. In our country we have seen many persons, just like Sir Gurudas Banerjee, Ishwar Chandra Vidyasagar. They had very good mothers, and they became very great men. Similarly, we saw one Englishman, Lord Willingdon, he had a very intelligent wife and he became great man.
So this prakrti is energy. By the energy of one woman, one becomes very great. That is the material arrangement. Not only material; in the spiritual world also the same thing. Just like Krishna is energized in the presence of Radharani. In the presence of Radharani. Krishna is called Madana-mohana, and Radharani is called Madana-mohana-mohinī. So the law is the same."
