Creators & Destructors of any universe

Annamayya sings about the configuration and functioning of universe, in one of his songs. He explains the details using Spiritual terminolog, though they have different Scientific terminology.

Song:        Okkadevvado Urviki Deivamu.  { song 333, volume 3 }
                  It is only one , Lord of this Universe.

In first stanza, he explains the functions of different Brahmas. Brahma is a “Gaint Power House” of Creation. There, in the centre of our universe rest 9 Brahmas. One Brahma is exclusively  for the creation of the different living beings. Another Brahma is for collapsing the cosmic structures. The 9 Brahmas stationed in the centre of the universe, sustain and empower the Universe. Every universe is Fete of many Brahmas. Annamayya says.....
        
                         “Vottina jeevula koka Brahma,
                          “ Nattanadumavaare nava Brahmalu”
                        “ Brahmalu Santhaaye Jagamu”

 In second stanza, he explains the functions of “.Rudras”. Rudra is a “   Power House of Destruction”.
Their are 11 Rudras and they  have supperate names.   “Siva” stays in a place Keilasam. Next stand other 11 Rudras, last one is “KalaRudra”. Fire is the form or Power of any Rudra. 
Our universe looks a Fete of  all these 11 Rudras along with Leader Siva.

                       Kailasamuna kaladoka Rudrudu, taalimi Ekadasa Rudrulu
                        Kala Rudrudu kadapata,  Rudrula Santayana Jagamu

In third stanza,  the protector of the universe is mentioned. The Sustaining Power is called Vishnu.
But the Protecter is the only one, the “Gaigantic Vishnu.”  This Supreme Power Vishnu is Spread all over the Universe invisibly.  On earth, the same Vishnu’s presence is  there in  Venkatadri.

Like this, universe is existing with the functioning of these three prime different powers, Brahmas Rudras along with Vishnu .
