Viahnu sahasranamam, slok107

Slok107:    SemkhabhrunnanDakee Chakree  SArngnaDhanvA  GaDAdharaha
                 RaDhamgapANi Rakshobhyaha SarvapraharaNAyudhaha

The Devine Supremo who holds, The  Conch PAnchajanya (Shankh), the revolving Disk with spikes of swords,
(SuDarshana Chakra ), the Bow SArgNa, the Club (Mace) KoumoDakee, who
handles the Chakras of the Transendental Chariot, the Defender who is armered
with all kinds of weapons for attack,  is Sree Maha VISHNU.

This slok is the replica of the "Nyasa" slok, in the starting of Vishnu sahasranamam, in which all these "Astras" ( weapons) are mentioned . All these  different shaped weapons of different energy forms, defend any devilish attacks on the Devine Field, VISHNU Khetra. The word "Ayudhaha" tallys with the word "Astraha" in NyAsa slok.
In 81st slok, one name of Vishnu is given
discriptively, as "SarvasasthrabhruthAm varaha". It means, the Great Transendental  Entity, consisting mutiple revolving weapons in it. Hence, the Supreme Commando VISHNU beholds multiple enery projections as weapons, in the " Revolving Circular Formation" to safe gaurd the thriloka kshetra.

The Eternal Blissfull  Devine Circular Khetra (field) of Supreme Consciousness and Rightuousness which is called  THRILOKATMA is ever
Protected by the Lord of Thrilokatma- VISHNU,  with the help of all above said
Devine  Astras. Vishnu is the Supreme Gaurd and Lord of the universe.

Om Vishnave namaha
