Vishnu sahasranamam, slok 102

Slok102:         ADhAranilayo  DhAthA  PushpahAsaha  PrajAgaraha
                 OOrDhwagaha  SathpaDAchAraha PrANaDaha  PraNavaha PaNaha

The  Supporter of  the universe, , the Sustainer,  the Flower patterned Formation, The Companion ,  the Life in all living beings,  the upper most celestial  existence,  the one traditioned in Rightuous Path,  the bestower of Life,  the mono syllable "Om", and the Lord of universe,  is Sree Maha VISHNU.

As said in many previous slokas, here too, Vishnu is designated as the single sacred syllable "Om".
Vishnu is the base resource of " Life Force"-which sustains life in all  living
beings. This  Power Bank supplies the Vital Energy, the "Life Force", to all creatures
living  in the universe. In this slok the prime factor helping for the Universal Sustainsance, the " Jeeva" or  "Life force" is emphasysed. " Life" is the first and foremost  disposition of Vishnu.   

Everything, in this creation, either stationery or mobile, holds invariably some unit of Charge.  Similarly, every action carrys charge and also ends with charge. This "Karmic current" is positive, when the action done is Rightuous and vice versa.This is a universal principle. Weather human or devine.  has to face the same consequences corresponding to their karmas and karmic results. 
This is an inevitable law of universe. Karma ( action ) dictates the Janma.
But, VISHNU is of all good charecteristics and rightuousness.
That's what this slok reiterates. Devinity means absolute "Purity".

VISHNU  IS ABSOLUTE PURITY.
