It is not always easy to be kind, but it is also not that difficult because kindness flows naturally from our beginningless non-dual nature. So if we remind ourselves constantly to be kind, we constantly put ourselves in closer contact with our primordial non-dual state. There is also something in the activity of kindness that has an effect on us. When we make the effort to be kind, we may find that it becomes increasingly effortless. It may begin to flow naturally, and make us glad that we can experience such warmth and openness. A truly kind act is an act of pure appropriateness and therefore whenever we are kind , there will be an element of appropriateness. Life will seem more infused with energy, and there will seem fewer obstructions. Kindness simplifies situations.
