Guru Maharaj: Somehow it says here,Vasudeva and Devaki, are the parents of Krishna, and Rohini is the mother of Balarama. Vasudeva and Devaki are the parents of Krishna. So just like Narada, he had some pastime before his liberation, so a person can also do some pastime with Krishna in the material world, and later be elevated to the spiritual world. The true parents of Krishna are Nanda and Yasoda. But this blessing was also given to Devaki and Vasudeva. Because the spiritual world is beyond time. In this material world we have past, present and future, but in the spiritual world, there is nitya vartaman. Eternal present. Therefore, there is no birth, death, old age or disease.
