"Without doubt, O mighty-armed, the mind is restless and hard to restrain; but through practice and dispassion it can be controlled."
Modern explanation
In the middle of the day, return to this: A restless mind is not a broken mind. Practice, patiently repeated, slowly bends it.
Practical application
Pause for sixty seconds. Feel your feet on the floor. Notice that this moment is, in fact, survivable.
Reflection question
If I removed the imagined future, what's actually happening right now?
