vāsudeva-the expansion named Vāsudeva; saṅkarṣaṇa-the expansion named Saṅkarṣaṇa; pradyumna-the expansion named Pradyumna; aniruddha-the expansion named Aniruddha; dvitīya catuḥ-vyūha-the second quadruple expansion; ei-this; turīya-transcendental; viśuddha-free from all material contamination.
Vāsudeva, Saṅkarṣaṇa, Pradyumna and Aniruddha constitute this second quadruple. They are purely transcendental.
"O my Lord, Your transcendental pastimes and enjoyments all appear inconceivable because they are not limited by the causal and effective actions of material thought. You can do everything without performing bodily work. The Vedas say that the Absolute Truth has multifarious potencies and does not need to do anything personally. My dear Lord, You are entirely devoid of material qualities. Without anyone's help, You can create, maintain and dissolve the entire qualitative material manifestation, yet in all such activities You do not change. You do not accept the results of Your activities, unlike ordinary demons and demigods, who suffer or enjoy the reactions of their activities in the material world. Unaffected by the reactions of work, You eternally exist with Your full spiritual potency. This we cannot fully understand.
