Happiness. (A Peaceful Mind and Body)
To be Happy, we must be able to Accept life as it is (right NOW). To truly Accept life, we must BE and Remain, absolutely Present in EACH inevitable moment.
The Body is the best Metric known to mankind. The Body is trying to remind us through our 5 senses, how Present and Aware we are [not]. The Body uses Pain and Pleasure to reclaim our Conscious Attention.
Subtle cues are missed over time, and become [obvious] surprises.
