Every movement you make is comprised of a varying degree of consciousness mixed with automatic anatomical functions in the body.
When you choose where you want to move the body, an automatic anatomical function is activated. Reciprocal inhibition is a process where one muscle contracts signaling its muscle pair on the same joint to release. This creates a give and go in the muscles of the body creating smooth and controlled movements. This is the body acting without consciousness.
When you engage movement consciously, precision of movement can be accomplished. Bringing your conscious attention to a movement can augment the powerful action of reciprocal inhibition creating more control through strength as well as greater flexibility in the release.
Yoga is a process of finding union. Mind and body is just one form of union in the practice of yoga.
Think before you move!
