“. . . according to the Yoga Sutra (3.1), the term [Bandha] refers to the ‘binding’ of consciousness to a particular object or locus (desha), which is the very essence of concentration.”

  8. I finally know what'is the "crunk!" that I hear when I describe large circle whith legs, in supine position. More than a sound, it's the clear sensation that "something" over to the joint ( not inside it) is moving and changing it's place. I started to hear it 25 years ago, and during all this time I have been in fear for it, because I thought it wasn't normal. Thank you, Ray! And excuse me for my bad English :)

  10. *IF* I stop at question #2, I'll have a perfect score of 100%. *IF* I continue beyond question #2, I'm 100% certain that I'll forfeit my 100% score! lol So, during this inordinately stressful time, I'm stopping at #2 and am going to go actually STUDY "The Anatomy and Biomechanics of My Psoas." :-)

  11. Enjoyed this, but is a correction required? Aren't both Psoas & Iliacus are Internal Hip Rotators (vs. external as your quiz suggests) ??
    Note: Gluteus Max. is the Antagonist (external rotation)

    Many thanks

    1. Hello Jorg,

      Most of my sources list psoas major as an external rotator, however it may depend on position of hip joint in cadaveric studies. I find no sources that list the psoas major as an internal rotator in any position. When the trunk is held in place, the primary function of the psoas is hip flexion, so the gluteus maximus is an antagonist for this action. With the hip in flexion and abduction, the GM would be a synergist for external rotation.
