Dear Cazzer,
Okay, so let's examine your question closer, break it down, and then see whether step-by-step answers help:
(1) is Pure Awareness focussing your attention on a specific thing for example your finger tips (2) or is it having no thoughts in your head (3) and focusing your attentin on the 'nothing' thats there instead?
1.
is Pure Awareness focussing your attention on a specific thing for example your finger tips?
Pure awareness is not an action or activity: it seems to be empty space, but it is also all potentials. You are confusing pa with the techniques Frank has developed which help us become aware of it. PA is not something you do. You are always in a state of awareness, but you are usually only consciously aware of a fleeting series of physical objects interspersed with thoughts in your mind; your mind focuses on the objects or thoughts themselves
and not the awareness allowing you to observe them or the spaces between them. 2.
or is it having no thoughts in your head and focusing your attentin on the 'nothing' thats there instead?
This is actually closer. If you get what I'm saying in 1., then let's rephrase the question: "Am I aware of pure awareness when I have no thoughts in my head?"
Well, it
is possible to have no thoughts in your conscious mind
without being aware of pa. An example would be when you are sleeping.
But when you are consciously aware and observing the space or "gap" between one thought and the next, you are aware of pa; or when you are juggling and expanding your conscious awareness to encompass multiple objects in acute detail, you are overloading your capacity to the point where you are increasingly more aware of your awareness than you are these multiple focal points or objects of awareness, and this so points to pa.
It is that moment between one thought and the next in which you are paying such close attention that you notice the gap.3.
and focusing your attentin on the 'nothing' thats there instead?
This is more like it, but it won't feel like you are "focusing on anything, and you won't be, because there is nothing (i.e. "no thing" / no object / no focal point) "there" to focus on. The Eufeeling emerges in response to this gap, because you become aware of awareness.
Keep at it: this will all make sense in time!
