By the mystic power of Nārada Muni, the living entity reentered his dead body for a short time and spoke in reply to Nārada Muni’s request. He said: According to the results of my fruitive activities, I, the living being, transmigrate from one body to another, sometimes going to the species of the demigods, sometimes to the species of lower animals, sometimes among the vegetables, and sometimes to the human species. Therefore, in which birth were these my mother and father? No one is actually my mother and father. How can I accept these two people as my parents?
