One powerful way to be happy is to remember how connected we are to our Source and to every other part of creation. This Unity is the only true Love there is. It is also our natural, unchangeable essence. So, when we stop judging ourselves and all others as being "not good enough" and start loving ourselves and all others, we are automatically happy because happiness is Who we are! The love we send out returns to us magnified. This is a universal law or truth.
The one absolute necessity for my own peace-of-mind in relation to others is acceptance without judgment. If I don't make the other person "wrong", I have no reason to be upset or emotionally disconnected from them.
Since earliest childhood, most of us are taught by our parents, teachers and clergy what is "right" and "wrong" and/or "good" and "bad". So we always felt judged by one person or another. These judgments we meant to keep us in line with what others wanted and to distract us from our true passions and creativity. Because we were judged, we believed it was OK to judge others and we created emotional prisons for ourselves and others.
Well, it's time for us to free ourselves, if we choose, to be who we have always been by discarding our labels and limitations and allowing ourselves and all others the freedom to be however we choose to be as long as we do no harm to another person or their property.
There's something to consider.
