The Buddhist nun, Pema Chödrön, has a nice analogy she uses. In Buddhism the journey toward enlightenment is often characterized as crossing a river on a raft to get to the other side. But how Pema has written she likes to think of it is that, halfway across the river, the raft overturns dumping us into the water. And we have to learn to float.

Another way Pema puts it is we have to learn to be "comfortable with uncertainty". As "PumpkinPieHead" wrote.., you really don't ever get to the "other side". But what you can do is to learn to float... to be comfortable just with the way things are in the present moment. It has been said, many times, enlightenment is a journey not a destination. My personal view, at least, is that the same could perhaps be said of recovery from mental illness.
