Krishna is complete and Radha is also complete. Krishna is the rasadhara of Radha and Radha is the undercurrent of Krishna. And they are the same. Therefore, even after separation, both remained at the spiritual level. Every man has a female and every woman has a male element. The difference is proportional. The male element is predominant in the male and the female element in the female. Lord Krishna was a perfect man. That is, there was no female element in them at all. Similarly, Mata Radha was perfect. That means complete woman.
