A heightened sense of awareness is all about the present moment. In heightened awareness the mind is not imagining all kinds of evils befalling us. It is at rest because it is conscious of so much more than the need to get the next task done so we can eat and keep our bodies alive. While in heightened awareness, we can still perform tasks, yet at the center of the activity is peace.
Heightened awareness takes us beyond and above our minds and attunes us to the harmony of the Universe. Fear is not a part of this kind of consciousness. Faith, trust, and humility become dominant as we see the unfolding magnificence of the Universe. We may be aware of fear as part of the emotional spectrum, but it does not take over.
