Awareness is the scope of a person’s consciousness. Awareness on the low end equates to sleep, while the highest awareness might include a total connection with the world, enlightenment, or peak experience.
It takes energy to raise a person’s awareness, and therefore most people go about their lives at the lowest level of awareness required to get by. This could mean that the person is conscious of only their own concerns or dwelling on the past.
A simple boost of awareness might include being conscious of the people around you and really trying to listen. It might also mean taking note of your current environment instead of being in such a hurry.
