When your daily activities that make up your practice become second nature, your practice becomes your flow.
When all of your attention can be on the activity without having to think about what to do and when your whole being becomes involved in the activity, it becomes effortless.
I first felt this long ago when I first started going to instructor-led fitness classes. All you needed to do was follow the instructor, you didn’t have to think about what to do next, you could simply lose yourself in doing the exercises. It became easy so that all your effort was on the exercise and it maximized what I got out of the exercises. The outcomes were much greater than if I exercised on my own.
That is the state we want to get to with our practice. The practice tells us what to do when we just focus on doing the activities.
