Since this is the meditation sub-forum I'll point to effortless meditation. All of that "dimming" of awareness/consciousness isn't really a "dimming" of awareness but getting caught up in doership, and letting go of doership is letting go of the overlay of Ahamkara/ego.

Even though the meditation is called Do Nothing, you’re actually doing a little tiny bit of something: you’re paying attention to the feeling of doing something.

You’re simply noticing when you feel that you’re doing something and letting go of that.

Letting go of doership is tricky because the usual way we let go of distractions when sitting is going back to attending the object of the sitting and A: that is doership; B: there is no object of attending in Do-Nothing. Ultimately it's not about letting go of doership, but not getting attached in the first place or more appropriately Realizing one is never attached to doership to begin with. Letting go of doership is probably what some call a higher level or expansion of consciousness and the more one lets go, the more expansive it seems but the change is not on the side of consciousness.
