When I meditate I feel lots of physical sensations which I often want to resolve or remove as they are not always pleasant, or I will get caught up in thinking about whatever comes into my awareness and lose my focus. If I remember to keep looking at the lights and where I am going, I am able to find my way back to the centre of my head, notice my breathing and create and destroy roses out in front of me, essentially not worrying about 'solving' anything I am experiencing. Lots of things are happening when I meditate but the quality of my meditation is revealed after I finish- i.e. in how I feel and how I 'am' as I go about my daily business after a meditation session.
Another interesting question is what are the headlights pointing at? Or to put it another way, where am I heading, what exactly am I focusing on and why am I meditating anyway? Why don't you see if any of the following ideas/metaphors about what the 'lights' are pointing at/shining on resonate with you:
