There is the description of a MAHAAVESHHNNU and VESHHNNU in the ancient spiritual text titled "Shreemada Daevee Bhaagawata".
It is mentioned therein that there is a TRELOKEE each in each "ROMA KOOPA" of the Lord MAHAAVESHHNNU. Each TRELOKEE is said to have its own holy trinity of BRAHAMAA, VESHHNNU and MAHAESHA/SHANKARA.
Now,let us go beyond the literal meaning of the dscription above.
Then,it would seem to indicate the phenomenon of the CLONING...!
Well,the holy trinity of BRAHAMAA, VESHHNNU and MAHAESHA/SHANKARA means the powers of CREATION, SUSTENANCE and DESTRUCTION. Now,each 'ROMA KOOPA" means the smallest living entity.In this case, it means the CELL.
"MAHAAVESHHNNU" may be taken to mean the MAANAVA [HUMAN] body.
Thus, it would mean that each CELL of the MAANAVA [HUMAN] body has the powers of CREATION, SUSTENANCE and DESTRUCTION. This means that each cell of the MAANAVA [HUMAN] body is capable of an independent existence like an independent TRELOKEE.This in effect means that each cell is capable of being GROWN/CLONED as the parent MAANAVA [HUMAN]body...!
