Vyūham — The Fourfold Emanations Presiding over Creation
Vyūham ('ordered expansion, systematic emanation') designates the second of the five modes of Bhagavān's manifestation in Viśiṣṭādvaita theology (the five being parā, vyūha, vibhava, arcā, and antaryāmin). The vyūha forms are four cosmic emanations of Vāsudeva (the supreme form of Śrīman Nārāyaṇa) who preside over specific functions in the creation, preservation, and dissolution of the universe.
The four vyūha mūrtis are:
- Vāsudeva — The first and supreme vyūha form, source of the other three. He possesses all six divine qualities (jñāna, aiśvarya, śakti, bala, vīrya, tejas — knowledge, sovereignty, power, strength, heroism, and splendor) in their fullness. He is the ultimate ground from which the other forms emerge.
- Saṅkarṣaṇa — Emanating from Vāsudeva, manifesting primarily jñāna and bala. He is the presiding power behind individual souls (jīvas) and the cosmic dissolution (pralaya). Associated with Ananta Śeṣa, the divine serpent.
- Pradyumna — Emanating from Saṅkarṣaṇa, manifesting primarily aiśvarya and vīrya. He presides over the cosmic mind (manas) and is the source of ethical teaching (dharma).
- Aniruddha — Emanating from Pradyumna, manifesting primarily śakti and tejas. He is the cosmic ego (ahaṃkāra) and the source of the material world's differentiation; associated with creation's material substance.
The vyūha forms are specifically associated with the Kṣīrābdhi (Milk Ocean) — the divine realm where Bhagavān reclines on Ananta Śeṣa in the form of the Kṣīrābdhinātha (Śrī Ālvandar, 'He who rules the Milk Ocean'). The deity at Tirukkuḍanthai (Kumbhakonam) — Āravamuthan (Āravāmuthan) — is understood as the supreme Vyūha Vāsudeva form.
In the Āgamic and Pāñcarātra worship system (which underlies Śrī Vaiṣṇava temple theology), the four vyūha forms correspond to the four directions of temple worship, to the four arms of the deity's anthropomorphic representation, and to the four cosmic epochs. The Divya Prabandham's praises of Bhagavān as He who reclines in the Milk Ocean are theological celebrations of the vyūha presence.
