The activities of the Lord are always wonderful. His personal servants Jaya and Vijaya were confidential friends, yet they were cursed, and they accepted bodies of demons. Again, in the family of one such demon, Prahlada Maharaja was caused to take birth to exhibit the behavior of an exalted devotee, and then the Lord accepted the body of Nrsimhadeva to kill that same demon, who by the Lords own will had taken birth in a demoniac family. Therefore, who can understand the Lords transcendental activities? Not to speak of understanding the transcendental activities of the Lord, no one can understand even the activities of His servants. In Caitanya-caritamrta (Madhya 23.39) it is said, tanra vakya, kriya, mudra vijneha na bhujhaya: no one can understand the activities of the Lords servants. Therefore, what to speak of the activities of the Lord? Who can understand how Krsna is benefiting the entire world? The Lord is addressed as duranta-sakti because no one can understand His potencies and how He acts.
