Jai Sri Ganesha,
In all the five elements exist the Brahma and these five element indulge keeping the spirit in mortal reality for a cause that best known to supreme Brahma,
Ocean and sky are far apart and in between lies the truth of air and earth, fire act as an intermittent element to cause fluctuation in their combo reality for embodied truth of Atman,
Fire exists in the Hiranyagrabh that cause the life and nature, Fire exist in truth of Yajna and act as carrier, fire exist in pyre to felicitate marks of existence of the spirit to create an positive aura for spirit to ascent to its respective realms,
All beings exist in reality of these five but remains unaware of their truth, but when human behaves same as other beings it truth create difference, man needs to wake up before it to late,
Jai Mahadev
