Parīkṣit Mahārāja's question to Śukadeva Gosvāmī was based on this principle stated by the Lord Himself in Bhagavad-gītā (BG 4.7):
- yadā yadā hi dharmasya</dd>
- glānir bhavati bhārata
- abhyutthānam adharmasya
- tadātmānaṁ sṛjāmy 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 (paritrāṇāya sādhūnām (BG 4.8)). Vāmanadeva, for example, appeared to save the devotee Bali Mahārāja. Similarly, when the Supreme Personality of Godhead accepted the abominable form of a fish, He must have done so to favor some devotee. Parīkṣit Mahārāja was eager to know about the devotee for whom the Supreme Lord accepted this form.
