Chatur Vyuha is the second state of godhead according to
Pancharatra Agama. The Agama expounds the Bhagavata religion of Vishnu worship
and speaks of five states of Srihari Vishnu. The five states are – para,
transcendent state pertaining to His abode called paramapada; vyuha, segmented
or self-divided state pertaining to manifestations of the God of paramapada
(Vaikuntha) for conducting specific cosmic activities; vibhava, state of
incarnation on earth; antaryami, state of immanent presence as controller of
all beings; and archa, state of presence of images of temples under worship.
Of these, the second, namely, the vyuha state is four fold,
one having four successive projections of Srihari Vishnu. Each projection
proceeds from the previous one of the Supreme One (called Paravasudeva residing
in paramapada and having infinite projection) whose six attributes suggesting
omnipotence and omniscience are notable. These are : jnana (knowledge), bala
(might), aishwarya (power to realize one’s wish), virya (effective force),
shakti (power) and tejas (luster).
The four vyuhas are named after Krishna, Balarama, Pradyumna
and Aniruddha, in that order, the latter three being Krishna’s brother, son and grandson
respectively. The vyuha are also considered to represent Paramatman, soul, mind
and ego.
The four-fold projections of Paravasudeva also have in them
implicitly all the perfection of the grand form. However, three of them
specialize in a certain perfection, pursuant to the functions they perform. The
four-fold projections and their respective functions are Vasudeva vyuha who has
all the perfection of Paravasudeva in the paramapada abode but reclines on the
milky ocean nearer the earth. He engages Himself as Ishwara, the source of the
universe as its creator, preserver and destroyer.
Sankarshana vyuha has jnana and bala as predominant characteristics
in consonance with His two functions namely withdrawal of the universe in pralaya
(epochal end) to its embryonic state and promulgating spiritual knowledge in the
form of the ekanti dharma (one-pointed life of devotion to Vishnu) for the
cosmos in the making.
Pradyumna Vyuha has aishwarya and virya pursuant to the
functions of producing the world of names and forms, and of fostering the
practice of ekanti dharma in the evolved world.
Anirudha Vyuha has shakti and tejas in consonance with His
functions of maintaining and protecting the world and leading the seekers to
liberation.
The three functions of withdrawal, creation and maintenance
with the parallel ones of promulgation and sustenance of dharma and of
liberation of humanity are allocated to the three pradurbhavas (emanations) of
the basic ground form, with division of attributes appropriate thereto. The
cosmic process involves creation, maintenance and withdrawal, with a new
beginning offering chances for spiritual activity and liberation, and is viewed
here as essentially redemptive in its nature. Thereby souls by practice of
ekanti dharma get a chance for redemption by the grace of Vishnu.
