One who equates Narayana even with great exalted demigods like Lord Siva or Lord Brahma is a pasandi, an agnostic. No one can equal Narayana. Nonetheless, Gargamuni used the word sama, meaning equal, because he wanted to treat Krsna as the Supreme Personality of Godhead who had become Nanda Maharajas son. Gargamuni wanted to impress upon the mind of Nanda Maharaja, Your worshipable Deity, Narayana, is so pleased with you that He has sent you a son almost equal to Him in qualifications. Therefore you may designate your son with a similar name, such as Mukunda or Madhusudana. But you must always remember that whenever you want to do something very good, there will be many hindrances. Therefore you should raise and protect this child with great care. If you can protect this child very cautiously, as Narayana always protects you, the child will be as good as Narayana. Gargamuni also indicated that although the child was exaltedly qualified like Narayana, He would enjoy more than Narayana as rasa-vihari, the central enjoyer of the rasa dance. As stated in the Brahma-samhita, laksmi-sahasra-sata-sambhrama-sevyamanam: [Bs. 5.29] He would be served by many gopis, who would all be as good as the goddess of fortune.
