just like a yoga teacher might tell you to relax your jaw or lower your shoulders when executing a challenging asana, the teacher in your own mind can learn to notice the tensions in your beliefs and actions, helping you to relax the "muscles" which didn't need to be pushing
this has huge consequences for your ability to more effectively be the person you want to be; when you learn to stop fighting yourself, much energy is freed up to be reinvested into ur growth
this has many connections to other practices, such as wu wei & the Alexander Technique
