sei sloke kahi bahyavatara-karana
panca sastha sloke kahi mula-prayojana
sei sloke—in that same verse; kahi—I tell; bahya—the external; avatara—for the incarnation of Lord Caitanya; karana—reason; panca—the fifth; sastha—and the sixth; sloke—in the verses; kahi—I tell; mula—the prime; prayojana—purpose.
In that verse I have also explained the external reason for Lord Caitanya's incarnation. But in the fifth and sixth verses I have explained the prime reason for His advent.
