What happens to dark souls

[jafar]

Given Mr Ra define 'higher self' as 6th density consciousness.
Then it will also eventually evolve to reach an 'octave'.
Back to the initial state, back to the first note in music.

The debate about higher self / atman is actually a 3000 years old debate.
Some view it exist in distinction from Brahman (ultimate reality), some view it is a form of identification of Brahman, some view it is Brahman, some view it doesn't exist.

Mr Ra seems to be within the view of higher self 'exist in distinction from Infinite Creator" and "a form of identification of Infinite Creator".

So I conclude that all souls, no matter how dark, eventually gets there

Fully agree, as 'soul' is merely a virtual sheathing (Maya Kosha) eventually the border of 'self definition' in separation to others will eventually be disbanded.

Mr Ra describe that the STS/STO merging happened 'earlier' when the consciousness evolve towards 6th density.
