Knowledge wears a grey suit.
Awareness has wings. :)
You can easily replace one with the other. Like you can say "I am aware of that" instead of "I know". However, when you are really aware, you know but you cannot explain how it makes you feel. When you are aware you know that knowledge is not everything. That there is a certain degree of levitation associated even with ordinary life.
Like knowing that water droplets run over a lotus leaf like mercury but then taking one on off on the tip of your index finger and feeling it!
Knowing that you breathe all the time in order to survive but closing your eyes and trying to follow your breath in and out of your lungs.
It could be knowledge and sensitivity together. It could be knowing with a flexible mind. More so a flexible ego. Better still, a flexible, knowing mind full of compassion. Is that awareness?
It is an evasive, ethereal word.
How would a Westerner react to "अहम् ब्रम्हास्मि।"?
If you translate it literally, it would be considered an expression of an inflated ego but I think it is closest to how we can explain awareness.
That is what separates scholars from enlightened ones. The fact that they are aware of the God within them!
