The easily attainable, the non-ostentascious, the all Accomplished, the Vanquisher of enemies, the destroyer of  the enimity, the Eswara of lower,
higher and other lokas, the killer of " ChANurAndhra", is Sree Maha Vishnu.

Nyagrodho : Anya + Agra + Adho = other + higher + lower Lokas

Vishnu is attainable only by true devotion. A pure self can alone realise Vishnu. To purify one self, one has to be very simple, and dedicated  to the
spiritual line.Then only, the purified self  connects to that " Absolutely pure self", ie Vishnu.
It is very impotant that one has to conquer the six enemies , "desire, anger, lust, passion, miserlyness and jeloucy", by constant practice. This is a very very tough practice. But not impossible. Simple way is observing, "detached attachment towards worldlly things". And also  practicing  Expectation- free attitude towards any action. This type of yogic mind realises that "Universal Mind", easily.

VISHNU is very near to everybody because exists everywhere. Vishnu is
within and without everybeing. Then, is there any doubt in attaining VISHNU,
when He is so close??

VISHNU's incarnation, Sree Krishna,  killed many rAkshas in DwAperayug.ChaaNuranDhra was one among them. VISHNU is KRISHNU.
KRISHNA'S DEVINE GLORIES ARE ONLY ENJOYABLE,  NOT COMMENTABLE.

OM VISHNAVE  NAMAHA
