We all use different strategies of perceiving the world, evaluating the impressions and deciding what action to take.
Some of the strategies we practice on and off the yoga mat are called proprioception, exteroception and interoception.
Proprioception is sensing where the body is in space. We sense position relative to other objects. Such as knee over ankle. Exteroception is perceiving the outside world through the five senses. Like using sight to check my alignment.
Interoception means sensing the internal world of the body, such as letting little adjustments happen, based on feeling the pose from the "inside out".
