Vishnu sahadranamam, slok82

Slok 82:    Chathurmurty rschathurbaahu schaturvyuha schathurgathihi
                   Chathuraathmaa chathurbhaava schathurveDa viDekapaath

The Brilliant figure,   the Strategic formation spread in four directions, the
Strategic final destination, the Great  Supreme Atma, the Supreme Intelligent
Mind, the essence of four VeDas, and the "Single Principle of Intelligence ", is Sree Maha Vishnu.

VISHNU is the only one "Transendental  Configeration", which is enveloping in all directions, splashing the true knowledge everywhere.
VISHNU IS  "CHATHRVYUHA, CHATHURGATHI". These two inanimate attributds refer to a Strategically Configurated Field ( Atma), which is cotrolled by the "Supreme Mind" and  "Supreme Consciousness."  Hence this " Devine Strategic Field "can be called" Vishnu Kshetra". .

VISHNU, beholds all  Supreme charecteristics of Abstract and Real nature.
Word" Chathurbaahu" should not be interpreted as a physical form with four hands. VISHNU, is " Chathurbhavaha".So, with which ever imagination, one
Worships, in that form only Vishnu appears. Vishnu is the Eternal Existance of Supernatural Devinity.. Impossible to give defined form to VISHNU.
Vishnu  is "the Eternal Principle," Chathur in every Aspect.      

Om Vishnave namaha
