Am I correct in my understanding that the Dreamer is the awareness of the nagal?
Yes! Remember always that the Dreamer IS the awareness, that is, the CONSCIOUS awareness of the indwelling spirit or nagal. And from this it follows that the TWO are ONE. But, by the same token, the nagal is an aspect of the Unspeakable, the INEFFABLE, about which we cannot even BEGIN to conjecture, and because of this we are FORCED to acknowledge that we do NOT know our TRUE SELVES beyond what the Dreamer is CONSCIOUSLY CAPABLE of, and can therefore guide the little self towards, and try to impress upon the little self!
