Passionless AND Present

Ever passionless, thereby observe the subtle.
Ever intent, thereby observe the apparent.

In my own pursuit of enlightenment, these lines from the Tao Te Ching have been key to me. I have taken these lines to mean that the passionless state, in which I can observe the subtle, was the preferred one (which is perhaps correct). However, I have long thought that the way to be passionless was to be UNinvolved in each moment- to be detached and observing as from above.

As I learn more about mindfulness lately, discovering its true meaning and implications, I have come to understand that being fully present in the moment IS the path to a passionless state. Rather than being incompatible, I see that the two are wrapped up in each other- being passionless helps me be fully present, and being fully present helps me to be passionless.
