Hi, vishnu is not going to take everying into his stomach.. the moola Shrikhara who is the creater of all gods including Lord Narayana.... Shrikhara is the parabramha..... people believe that parabramha dont have any shape and only shakti... initally Shrikhara was not having shape... but later Shrikhara Shakti took the God form of Shrikhara. Then he created everying.... their is nothing like Pralaya and all. Once created it created. No taking back....
