There isn't any specific mention from what I gather.
However,what you mention is very useful and not far off. There are mentions of the ''void'' and the ''primal void''.
With various shabads, I personally have concluded or understood that this ''void'' which contains nothing, just as before the creation was created.
Infact contains more than everything!
In effect, the ''Nothingness'' that is within everything and surrounding all, is infact ''Everything'' - This 'Everything' does not need be physical matter with the molecules we know, but it is ALL and the ONE, the Ek Onkaar!
Just my personal observation, never read it or heard it!
Waheguru
this is a very interesting subject.
When i think of my own consciousness...i only know that i exist if i have sense perception...i.e. i can see, hear, touch etc.
if someone hits me over the head with a baseball bat...all sense perception is lost...i become unconscious....have no idea i exists.
Therefore for consciosness to exist....there must be something to be conscious of.
so creation and creator must co-exists at all times...even the void (before creation as we know it) must have contained something (whatever that may be) for totality of conssciousness (god) to exist.
Nice post lucky ji.
