I loved the “monkey bars” when I was a kid. Grasping onto one bar, swinging to the next, moving along. We used to challenge ourselves to skip increasing numbers of bars. First, a hand on each bar, then skip one between grasps, then two, and finally three. None of us on the playground could go more than 3 bars, as our arm length was a finite limiting factor.
Since then, I’ve used this activity as a metaphor. In order to move forward, one must release their grasp on the hand in back. Only by releasing what is behind, the past, can one be fully moving in the present and able to progress. And of course, just as soon as one arrives in a new place, its time to let go again. Infinite opportunities for practice! Catch and release of a different sort.
