AFTER VEDANTA : ( Taittiriya Upanishat )
[As I Understood]
==================================
The Bhu( Earth ) , the Bhuva (Solar space or (Sky) and Swar (the  Space  of  outer Gakaxies , beyond ) make the Cosmos .
( They are all different Fields of 'Vibrations ' . }
* ' Matter is  frozen Energy when they lose the speed of Light ' - Einstein 

[ ' Only 6 % of the Cosmos is accounted for by Matter ; rest is Dark matter 4%  or Dark energy 70 % ' ----- says Cosmology .]

Every ' thing' in the Universe(s) is 'Food' only [ Matter to Mouth; mouth to matter --HGT ].
" Royeerbaa Etat Sorbom Yot Murton Vaa Vimurton Cho " (sanskrit in Roman script & phonetic selling )
[Transliteration : Everything including all matter , Visible -Invisible in the Universe , is 'Food' for some  one  or  some thing else and subjected  to   Law of ENTROPY( Cosmology /Physics )]
Even wood is food for termite; even metal is food for weather .
[ Time is the ' Eater' of everything   too- Pibi ]
----------------------------------------------------
Before this ' Cosmic -Cycle ' Brahman ( Divine ) Existed as UN- manifested .
Everything small ( sub-atomic) to big ( Galaxies) is bound by COSMIC- LAW.
-----------------------------------------
Father Varuna taught his son Bhrigu thus : ---" First Learn About Food and seek it through Meditation ".[ Transliteration ]

The hungry has as much right to the food as the rich .
ALL LIFE IS ONE .
