A pure devotee never wants to see the Lord unnecessarily. The Lord is engaged in various activities, and the pure devotee does not want to see Him whimsically, for his own sense gratification. The pure devotee simply depends on the Lord’s mercy, and when the Lord is pleased, he can see Him face to face. The Lord is unseen even by demigods like Lord Brahma and Lord Siva.
