'dvitīya catur-vyūha' ei--turīya, viśuddha
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.
Saṅkarṣaṇa, the second expansion, is Vāsudeva's personal expansion for pastimes, and since He is the reservoir of all living entities, He is sometimes called jīva. The beauty of Saṅkarṣaṇa is more than that of innumerable full moons radiating light beams. He is worshipable as the principle of ego. He has invested Anantadeva with all the potencies of sustenance. For the dissolution of the creation, He also exhibits Himself as the Supersoul in Rudra, irreligiosity, sarpa (the snake), antaka (death) and the demons.
