bhakta-premāra yata daśā, ye gati prakāra
yata duḥkha, yata sukha, yateka vikāra
kṛṣṇa tāhā samyak nā pāre jānite
bhakta-bhāva aṅgīkare tahā āsvādite
bhakta-premāra—of the ecstatic emotion of the devotee; yata—all; daśa—conditions; ye—which; gati prakāra—mode of progress; yata—all; duḥkha—unhappiness; yata—all; sukha—happiness; yateka—all; vikāra—transformation; kṛṣṇa—Lord Kṛṣṇa; tāhā—that; samyak—fully; nā pāre jānite—cannot understand; bhakta-bhāva—the mood of a devotee; aṅgīkare—He accepts; tāhā—that; āsvādite—to taste.
Kṛṣṇa Himself cannot fully understand the conditions, the mode of progress, the happiness and unhappiness, and the moods of ecstatic love of His devotees. He therefore accepts the role of a devotee to taste these emotions fully.
