The comments to the last post are so good that I'd like to keep the conversation about goals going. Zen liturgy and commentary have a lot to say about goalless goals. For example, this is from the Sandokai (best known in English as Identity of Relative and Absolute), an 8th century Chinese text by Shitou Xiqian:
Make no criterion: if you do not see the Way
you do not see It even as you walk on It.
When you walk the Way, you draw no nearer, progress no farther;
who fails to see this is mountains and rivers away.
In his commentary on this text (working with a sightly different translation), Shunryu Suzuki Roshi said,
"'Practice is not a matter of far or near.' This is very important . When you are involved in selfish practice you have some idea of attainment. When you strive to reach a goal or attain enlightenment, you naturally have the idea 'I am far from the goal,' or 'I am almost there.' But if you really practice our way, enlightenment is right where you are." [from Branching Streams Flow in the Darkness: Zen Talks on the Sandokai]
"'Medicine and disease cure each other.' 'The entire great earth is medicine.' What particularly is oneself? The Cure."
The entire great earth is medicine. Everything is medicine. But then it also says that medicine and disease cure each other. It's not a matter of using medicine to drive away the disease. As I understand it, the "cure" is a kind of resolution, of both medicine and sickness.
Another translation of this passage is "Medicine and sickness subdue each other. The whole earth is medicine. Where do you find yourself?" Where do you fit into this sickness-and-medicine thing? How can you be the cure? That appears to be the question the koan is asking.
Be advised that this is a koan that's been nagging at me for years, but I've never formally presented it to a teacher. So anything I say is an uninformed student's opinion and not an expert's word. But, at its most basic, it seems to be saying, "Don't sort everything into 'sacred' and 'mundane' (or good/bad) bins. Don't make a duality out of practice and enlightenment. Don't think of anything as separate from you."
Roshi also wrote that "A beginner's practice and a great Zen master's practice are not different." However, if you think practice is something you do to obtain enlightenment, that is delusion. You will be creating huge barriers for yourself.
