Here is Asteya one of the Yamas from the ashtanga yoga eight limbs. This is from Sharath's book Astanga yoga Anusthana .   I have heard him discuss some of the things mentioned here, including the stealing of poses.

My take on these, is to practice to the best of my ability in the same way as I practice Asana ( Yoga poses).
