Consciousness in itself can only be known as an observer, because the observer which watches is pure consciousness, not the brain. In fact, the brain's energy is consciousness itself.

You want to know what consciousness is? Meditate. That's all. Scientists have been told this by yogis who've realized the true nature of reality but still ignore it due to the presumption that reality is material, when in fact, it is made only from the mind. If science has a certain way of thinking and belief, and isn't open to the fact that reality may be, in fact, divine, due to ideas and notions, beliefs and thought patterns, then it's the same as a religion.
