I don't know if this question suits this site or not or whether it's a stupid question but I want to know that has there been any incident in scriptures where someone asks god for a boon that is as follows:
''Hey god I want to become Parabrahman just like you. Grant me one of the positions of parabrahman like Shiva, Vishnu, etc. or make me a separate deity.(not like a devata)''
Is there anything mentioned about this? I have also heard something regarding Purushamedha and Sarvamedha Yagnas in this context. What role do they have here?
