From a point on the compass
To magnetic north
The point of the needle moving back and forth
From the point of entry-
Until the candle is burned
The point of departure is not to return
I have always loved these ones, too. I like that the last line of that stanza, and the one that mirrors it - "the point of the journey is not to arrive" both have a double meaning. The point of departure is the exact place that the journey starts, so it is behind you once you start, and therefore does not return. But also the point, as in the prescribed meaning, is to keep going...to not return. I love that.
