Pema Chodron could be writing about riding

Pema is one of my favorite authors, and every time I re-read one of her books, I learn something new. In "The Places that Scare You: A Guide to Fearlessness in Difficult Times", the Prologue reads like it was written for a rider:
"As the Zen master Suzuki Roshi put it, 'In the beginner's mind there are many possibilities, but in the expert's there are few.'
... the three noble principles [are]: good in the beginning, good in the middle, good at the end. We can begin anything we do ... with the intention to be open, flexible, and kind. Then we can proceed with an inquisitive attitude. ... 'Live your life as an experiment.'
At the end of the activity, whether we feel we have succeeded or failed in our intention, we seal the act by thinking of others ... [and] [w]e wish that anything we learned in our experiment could also benefit them.
In this spirit, I offer this guide on the training of the compassionate warrior. May it be of benefit at the beginning, in the middle, and at the end. May it help move us toward the places that scare us. May it inform our lives and help us to die with no regrets."
