Very nice article about awareness vs consciousness
key sentence :
when the awareness touches the object it becomes consciousness.
is all the more important when you realise that in french they often switch one with the other while translating original articles, or talks.
even the word awareness happens to be translated as consciousness..
What is Consciousness vs. Awareness?
What  is consciousness? Science seems perplexed when it has to
 address this question  because it really doesn’t have an answer. But 
according to Buddhism, the  appearance of objects in the mind is known 
as consciousness. You can also say that the conceptualization of   
objects within/as consciousness is known as “mind.” Without that content
 we colloquially say there is no mind. 
Before  the appearance of objects we still have awareness, but it 
is empty. Awareness when it touches  objects becomes consciousness. So 
awareness without objects is the aprior state  before consciousness and 
is the ground state that “supports”  consciousness.  Awareness is always
 empty in a not-knowing state. It just shines or illuminates.  That’s 
called effulgence, which means radiance, brightness, illumination or  
shining. Without touching objects, awareness just remains in its own 
body and  shines, it be-s itself, it just is. That’s “presence” or 
being. That’s also  self-effulgence so effulgence is the nature of 
awareness. It’s like a great  bodyless body of not-knowing knowing. You 
cannot identify it as either existence or  non-existence, as either real
 or not real because it transcends all these  descriptions. It is 
without these two attributes because that is its purity. Awareness  is 
an ever shining function of our real ultimate essence of being. It 
allows us to know and understand because it allows us to be aware of 
consciousness - all the moving stuff.
On  the other hand, “our mind” is something more objective because
 “mind” means clear  differentiation and understanding. “Mind” involves 
clear discrimination—that which  discriminates the characteristics of 
objects. So we use the mind to understand  things because mind 
understands the manipulation of consciousness. Mind is a pattern of  
consciousness which is born from awareness which is in turn a function 
of our  original nature. At least that’s the explanation of Buddhism and
 Advaita  Vedanta, which have had thousands of years to work out robust 
definitions and  explanations. 
In  terms of the teachings of spiritual schools, consciousness 
isn’t yet our  ultimate ground state of being because consciousness 
knowing isn’t our ultimate  original nature; it is a looking outward to 
objects rather than a state resting  in itself as its real essence 
without elaboration. We mistakenly think that  knowingness or 
consciousness, which we colloquially term the “mind,” is our  real self 
but it is not. It cannot be because it is inconstant and does not  
always stay. It's just flitting all the time. There is still something 
ultimate behind consciousness, there is something  that transcends the 
oridnary mind, there is still something behind knowing and what is  
behind it that spiritually transcends it is ever present, never moving, 
always  empty, shining awareness. In fact, the highest secret of the Zen
 school of Buddhism is that our consciousness and  then even awareness 
are not the ultimate, fundamental “host” or “Self.” Consciousness  and 
awareness are still a “guest,” they are still a function of the Absolute
  nature. 
The  realm of consciousness is only a projection of the original 
nature. It’s still  a dependently existing construction, which means it 
depends upon other elements for its  existence. It is just a function of
 the original nature, or God, or Self, or however you wish to word it. 
And because consciousness depends upon other things for its existence, 
it  cannot be the ultimate state of reality. As to the actual  realm of 
the enlightened, the Buddha  Manjushri said, “It is not something that 
can be known by consciousness, nor is  it an object of the mind.”  It 
transcends consciousness, it is aprior. You cannot find This Ultimate 
One with the mind of  thoughts, so how do you find It? By no-mind, 
no-thought, by not attaching to  thoughts but letting them just be there
 when they are, but never attaching to  them while maintaining presence.
These are deep words that science has not yet  fathomed. At best 
psychiatry and psychology deal with the mental events of the  mind, 
trying to put them into groups having this or that shape or meaning.  
Cognitive science is still puzzling how objects “out there” turn into 
mental  events inside the brain and then consciousness, so it has not 
proceeded far in  this direction either. In this new century, the best 
advice we can give  neuroscience and cognitive science is to examine the
 ancient schools of  Buddhism and Advaita Vedanta to discover what they 
have to say about  consciousness and the many various modalities of the 
mind.
