Growth can often involves a letting go of old ways, especially those that have ceased to serve. However, when we are in the midst of it, it can be hard to appreciate it in this way. We are more inclined to hold on to what is familiar and keep to what we know. However, sometimes the depth of new life can only be seen when the current one is broken open. It is true that there are occasions when we only grow when we pass through difficulties. With growth we move toward fuller healing and wholeness. It’s as if they had been waiting all along, until you made room for them to come into your life.
The world, I’ve come to think, is like the surface of a frozen lake.
We walk along, we slip, we try to keep our balance and not to fall.
One day, there’s a crack, and so we learn that underneath us — is an unimaginable depth.
James Joyce, The Dead

From a meditative perspective, various mind states including emotions, arise and pass away empty of any substantial nature. They come into being when certain conditions come together and disappear when the conditions change. None of them belong to anyone; they are not happening to anyone. In a very real sense each mind state is expressing itself: it is desire that desires, fear that fears, love that loves.
