Lecture Srimad Bhagavatam 3.15.42
By His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
(Narayana is more beautiful than Laksmi, Krsna is more beautiful than Narayana, and Radha...)
The beauty of the Lord [Narayana] was so enchanting that it could not be sufficiently described. The goddess of fortune is supposed to be the most beautiful sight within the spiritual and material creations of the Lord; she has a sense of being the most beautiful, yet her beauty was defeated when the Lord appeared. In other words, the beauty of the goddess of fortune is secondary in the presence of the Lord. In the words of Vaisnava poets, it is said that the Lord's beauty is so enchanting that it defeats hundreds of thousands of Cupids. He is therefore called Madana-mohana. It is also described that the Lord sometimes becomes mad after the beauty of Radharani.
Poets describe that under those circumstances, although Lord Krsna is Madana-mohana, He becomes Madana-daha, or enchanted by the beauty of Radharani. Actually the Lord's beauty is superexcellent, surpassing even the beauty of Laksmi in Vaikuntha. The devotees of the Lord in the Vaikuntha planets want to see the Lord as the most beautiful, but the devotees in Gokula or Krsnaloka want to see Radharani as more beautiful than Krsna.
