So the whole universe is one body?

[Ashim]

I thought you lose your identity at 8th density, and starting to at 7th. Though you are still you, correct?
And don't you approach 7th density as a social memory complex rather than as an individual?

Identity simply means that you associate with one portion of the creation more than the other. This is a distortion.

Having no identity does not mean that you stop existing, it means that you no longer identify with one group over the other, or that you have no bias.
You still remain a soul with free will.
If you are able, at will, to 'walk in' or become an avatar you will have infinite 'identities'. Thus many beings choose to have no name and be recognized simply by their energy signature.
The social memory complex is the 'inhabitants world' of the planetary Logos, by definition 'one' being, eg: Lucifer, Yahweh, Ra, etc.
If you are a planetary Logos then you have a social memory complex 'dragging' behind you, so to speak. Your 'family'.
