Being so favored by the Lord, Brahmā’s schemes and plans are all infallible. If sometimes Brahmā is seen to be bewildered, as, in the Tenth Canto, he is bewildered by seeing the action of the internal potency, that is also for his further advancement in transcendental service. Arjuna is found to be similarly bewildered. All such bewilderment of the pure devotees of the Lord is specifically meant for their further advancement in knowledge of the Lord.
