this! all of my favorite zen teachings describe it as 'your practice'. Zen Mind Beginners Mind says something like "in the mind of the expert there is only one path, in the beginner's mind there are many" and urges the zen practitioner to always keep the beginner's mind... It emphasized to me that it should be _your_ practice of the teachings, not just inhaling more and more teachings
Reading is just another kind of attachment. You have to practice, even and perhaps especially when it seems challenging and difficult. Most spiritual traditions are very clear on this, including yoga itself.
