All things in our life experiencing can be reduced down to two things, Unity and Division. Through our moment by moment life experiencing, everything we think, do and say is either contributing towards Unity, or Division.
Are you bringing people together, promoting getting along in harmony, or are you putting up barriers and wedges between peoples causing separations, distrust, anger, fear?
You can, of course, choose which you contribute to, but I strongly suggest putting your energy towards Unity more than Division.
Be mindful through out the day of what you say, think and do. Observe where you are on the scale between total unity and total division. You can adjust towards one or the other, but it takes presence and here now awareness to consciously do so.
It is your life, consciously live it and consciously create the future you want to step into.
