As my teacher Scott Anderson originally pointed out to us: when a student laments shoulderstand because it hurts their neck, often what is really happening is that the pose is highlighting preexisting stiffness in their neck.
So it isn’t the experience [of shoulderstand] that is causing the pain, but the pain becomes obvious because of the experience.
If a boat has a hole on dry land, we may not notice the hole. However, place the boat in water and suddenly we observe water swirling around our ankles. Was it the location of the boat in the water that caused the hole? Or did placing the boat in water simply highlight the preexisting condition.
