There is not One Almighty, Overseeing, Omnipotent, Being . . . rather we are all our own god. What most indoctrined/religious people refer to as god is simply the Objective Universe / Natural Laws and Principles.
Find out who YOU are . . . you will find your God Within.
This is my problem with your words: you feel you can own it.
Will you look into this? Is it actually the case? You take an aggressive route to God, your ego wants to be victorious, it doesn't work like that.
You have to cease as you are for truth to arise in you, it will be your death as you are now, but you will know your true self for the first time then.
You have said you have encountered this, yet you say you do not think anyone can reside in it, will you see if you can reside in it longer by not allowing mind to come back in? To simply enjoy the state, but constantly remaining conscious that this is what you are?
It is difficult at first, you will fall quite often, but eventually it pervades through all events. Now you can even begin to go to sleep being aware "sleep is happening", if you repeat this for a few months something amazing happens: you are even aware in sleep. Now you have found that which is unchanging, this is the witness, it is the true or Higher Self - that which is aware of all that the Lower Self does.
Other than this, we agree on much, you are on the right path in general. You just have to realize the Higher Self is not part of the Lower Self. It is not bad you call it this, you just have to look more closely at that Self.
It is better to say Higher Self than God, for the latter will cater even more to the ego, but both are the universal consciousness. It is your own truth, but it is also everyone elses, for it is the very nature of our consciousness which is sought.
If you do not feel this is so, it is ok, just keep trying to find from where your thoughts arise. Do not simply say the brain, for the brain is much like an antenna, it receives signals and tunes into whatever channels appeal to it. Find out from where the signal comes.
