If I asked you to imagine you are sitting quietly on a mountain, overlooking a valley of tall and elegant trees... I suspect you'd have no problems imagining that! Not only do you have that picture available to you in your waking life, you have likely been cued to imagine something similar to that in the context of practicing Yoga. It is a common strategy to use imagery that evokes some quality within us that perhaps a more narrative or linear approach does not.

Imagine you are sitting quietly on a mountain. Stay with that image, please.
