The Creation?

 "First in the creation was the universe in the shape of an egg. Then came the energy. The universe exploded due to the energy. From the energy, the aspects of creation, sustenance and destruction were born"

Then Adi Shakthi exploded the Brahma Anda (“universal egg”), which burst with the sound of “Oum” (also spelled “Aum” or “Om”). That is how the creation started.
