If you peel off all, 

what remains is a peal of 

-----------laughter, 

after theists' bhakthi, shradha, tapasya, vratha, sadhana, 

god reveals his real , sath chith anand ,no name no form 

chithananda roopa 

shiviham shivoham

aham becoming shivam 

shivam is all goodness

i becoming all goodness

it's real godness 

this is the evolution of theist into atheist, 

''god'' disappearing in his final real appearance

in the beginning it is mystery

at the end it is mastery

having graduated mystery of theism 

one becomes a master,
