ParÄ«ká¹£it MahÄrÄja’s question to Åšukadeva GosvÄmÄ« was based on this principle stated by the Lord Himself in Bhagavad-gÄ«tÄ (4.7):
yadÄ yadÄ hi dharmasya
glÄnir bhavati bhÄrata
abhyutthÄnam adharmasya
tadÄtmÄnaá¹ sá¹›jÄmy aham
“Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion — at that time I descend Myself.†The Lord appears in each incarnation to save the world from irreligious principles and especially to protect His devotees (paritrÄṇÄya sÄdhÅ«nÄm). VÄmanadeva, for example, appeared to save the devotee Bali MahÄrÄja. Similarly, when the Supreme Personality of Godhead accepted the abominable form of a fish, He must have done so to favor some devotee. ParÄ«ká¹£it MahÄrÄja was eager to know about the devotee for whom the Supreme Lord accepted this form.
