"The only reason we don't open our hearts and minds to other people is that they trigger confusion in us that we don't feel brave enough or sane enough to deal with. To the degree that we look clearly and compassionately at ourselves, we feel confident and fearless about looking into someone else's eyes."...so said Pema Chodron, an ordained buddhist nun.
Look at the picture above, and we see how big our hearts were as little children, engulfing the entire body. In fact we were only heart+head. As as we grew older, the head and the thoughts in it, took on more prominence. The heart began shrinking in correspondence. We gave more importance than was needed to fears, failures, drop in confidence, opinions of others, and similar negative thoughts.
Realise that there are no failures in life...only experiences that we have to learn from. Realise that other people also have the same fears we have. Each of us is created special, and filled with our own brand of talents and abilities. Let us practise being happy with the way we are, and be brave enough to open our hearts to others.
