Dream Seed - Sound of Light (Full Album) - A Shamanic Sound Journey

शब्दप्रकाशः(shabdaprAkashaH)(Sound of Light)

Most of us would have heard of Shabda-Brahman --The Sound of Brahman, which is known as ॐ AUM.

But what about the शब्दप्रकाशः(shabdaprAkashaH)---The Sound of Light?

Seems strange right? That Sound of Light when both travel at different speeds?

Light does not need a medium to travel but sound needs a medium to travel.

This too makes us wonder about AUM which is Shabda-Brahman --(The Sound of Brahman) ...Is it the sound of Saguna Brahman or Nirguna Brahman?

For sound to travel we need a medium hence creation of matter of some sorts should be existing.
So technically it has to be the Sound of Saguna Brahman because Saguna is post- creation.

Also for a sound to be heard, we need a source of sound, medium to transmit it and something that perceives the sound by hearing or by feeling the vibration.

If there is nothing or no one to hear or feel the sound  goes "unheard".

For eg we humans can't hear the frequencies that dogs hear, so those frequencies go unheard by us humans though the sound exists.

So it seems clear that AUM most probably must be the Sound of Saguna Brahman.

Next question? What is the Sound of Nirguna Brahman? The state where creation had not yet taken place?

Absence of  matter, no one to hear the sound and neither a reason to have a sound.

It might seem  to be a शून्य(shUnya) a void ! No sound (शब्द:) nor light (प्रकाशः) exists.
So what say you?
Lord Buddha got it right? Shunyavada anyone?
