Gargamuni indirectly disclosed that Krsna was the son of Devaki, not of Yasoda. Since Kamsa was already searching for Krsna, if the purificatory process were undertaken by Gargamuni, Kamsa might be informed, and that would create a catastrophe. It may be argued that although Gargamuni was the priest of the Yadu dynasty, Nanda Maharaja also belonged to that dynasty. Nanda Maharaja, however, was not acting as a ksatriya. Therefore Gargamuni said, If I act as your priest, this will confirm that Krsna is the son of Devaki.
