“One may wonder if God is unlimited and self-satisfied, why does He need any beloved to satisfy His desire? To this the Brahmanda Purana states, radha krsnatmika nityam krsno radhatmako dhruvam, ” Lord Krsna is the unlimited God. When He wants to enjoy He manifests into His beloved, Radharani, and enjoys Her company. Therefore Lord Krsna and Radharani are eternally one and the same.” Lord Siva states in the Sammohana Tantra thus, tasmaj jyotir abhud dvedha radha-madhava rupakam, “The Supreme Lord Sri Krsna, although one and alone, He becomes two—Radha and Madhava (another name of Lord Krsna) just to perform His loving pastimes.”

While Srila Vyasadeva was writing Srimad Bhagavatam and explaining Krsna’s romantic dance with the Gopis He was meditating on Srimati Radharani, but due to fear of falling into trance he did not directly mention Her name in the Srimad Bhagavatam. The name Radha is very sensitive, if by chance Srila Vyasadeva or Sri Sukadeva Goswami would have repeated it, the Srimad Bhagavatam would have not been completed. Furthermore King Pariksit, the listener of Srimad Bhagavatam, only had seven days to live and was anxious to hear it in its totality, therefore Sri Sukadeva Goswami was afraid to mention Radharani’s name because if he did he would have gone into a trance. That is why Her name is not directly mentioned either by Srila Vyasadeva in writing, nor by Sri Sukadeva Goswami while speaking the Srimad Bhagavatam. In this way, Radha’s name is kept concealed in the Srimad Bhagavatam. In the previous volume we have described in more detail why Radharani’s name is not mentioned in the Srimad Bhagavatam.”
