Your "Sound of Yoga" workshop was an uplifting and wonderful experience. You describe symptoms and difficulties with speaking out that resonate with me.
After the workshop I was thrilled to find space in my voice box, seriously!! I feel that I gained a space, which somehow translates as a moment in which to think clearly and feel confident before vocalizing my thought.
I would highly recommend the workshop to any level of yoga student who has a desire to empower their thoughts and speech.
Best thing of all though was that benefit arose while having musical FUN.
